• 131 Rerun Badge Transparent Chrysler
  • 13.1 Challenge Race Keychain




This product is a unique one, so please read carefully. You can register for the Half-Marathon Rerun if you have previously purchased AMAZING, AMAZING WITH TWEAKS, EXCELLENT, or SUPER EXCELLENT and you want to follow the exact same 20-week plan for your upcoming training cycle.

If you have not previously purchased one of those plans, you are not eligible for RERUN—but we’d still love to have you in heart rate training! Please check out your half-marathon options.

When you purchase a RERUN, you will not have the Training Plan + Training Peaks tabs under the RERUN badge in your Train Like a Mother account. Those tabs, however, will still be under the badge from your initial purchase, so if you need to access them again, you can easily do so.

RERUN of course, has access to all the support, teamwork, advice, and coaching via Facebook, office hours, podcasts and biweekly newsletters that include both good-to-remember and brand new content.

Not sure if you’re eligible for a RERUN? Email us; happy to help!

Product Description


  • A Heart Rate-Based Half-Marathon Plan. Because you are repeating a plan you have previously registered for, you already own the PDF of the plan. (If you need to reprint it, simply go back to the badge in your Train Like a Mother account and the most recent version of it will be there.)

  • Miles of Resources. Your registration gets you access to the Train Like a Mother private site, where you’ll find helpful articles; video demonstrations of strength training moves, foam rolling routines, and running drills that are totally doable (read: less than five minutes! truly!) and will keep you running strong and injury-free; and plenty of other tips and tricks to compliment your heart rate-based training.

  • Exclusive Train Like a Mother Podcasts. We’ll answer individual training questions—and entertain you on your runs. Your first podcast will be a Heart Rate Training 101, which will explain many of the tenets you’ll use in this program. After that one, we’ll pull in experts, answer questions, help you thrive. As always, no question is too basic or TMI.

  • Accountability—and Camaraderie—Galore. In addition to Train Like a Mother Club, you’ll be invited to join a private Heart Rate-Based Marathon Challenge club on Strava, where you can track your miles, and a private Heart Rate-Based Marathon Challenge Facebook page, where you’ll quickly find an army of (funny, empathetic, inspiring) #motherruner teammates. You’ll share training tips, stories of good runs and bad, cheer each other on, and push each other out the door. Momentum comes from teamwork, and these Challenges roll on some serious #motherrunner momentum.

  • Expert, Accessible Guidance. We pop in via email at least weekly—usually twice a week—with a newsletter, as well as have a weekly Q+A with Coach MK, gear giveaways, and discounts on training essentials. If you hit a speed bump too big for a Facebook or Strava post, Coach MK has weekly office hours for individual questions. We want you to succeed, and want to offer every tool we can to help you.

  • A Training Peaks Account. This comprehensive training tool will help you (and us) analyze your data and chart the nearly daily growth of your endurance base. It also sends you a daily email with your workouts for today and tomorrow so you can plan accordingly. Because you are registering for a plan you have already done, you should have the plan accessible in your Training Peaks account.

    Best.Swag.Bag.Ever. This program is cheered on by the Chrysler Pacifica, a hybrid van as efficient as you are. To celebrate the miles together, you will receive an exclusive another mother runner keychain in your swag package!  You’ll also be getting our favorite training essentials, including a tube of Nuun, packets of GU, a pair of Balega socks, and samples of SweatX sports detergent and Chosen Foods Avocado Oil. We’ll also include an AMR teal rubber bracelet, so you can let the world know you’re a BAMR! (Shipping of $7.00 on U.S. orders and $15 for international orders will be added to your registration at checkout to cover the cost of getting these goodies to your mailbox.)


  • How will heart rate-based training help me become a better and faster runner?
    The plans dial in —or simply develop—an endurance base, which will help your running economy skyrocket and make you a capable, strong, injury-free runner. Think of a pyramid; the wider its base, the higher its apex can be without tipping or crumbling. Same with running: the wider your endurance base, the higher or faster you can run.

    Unfortunately, developing the endurance base is the process most non-elite athletes skip when decide to train for a half- or full marathon. They substitute other activities for easy runs or take the “easy” out of their easy runs. Either way, they don’t get the physiological benefit they need to finish the race feeling strong and healthy.

    Most runners devote a lot of energy looking for the Magic Workout, believing it’s something that involves the track and/or really challenging paces. There is some magic in pushing your paces, but only—and this is a big ONLY—if your body has a developed endurance base and is ready for the more intense work.

    I—MK—know plenty of runners who have been logging miles for decades in search of the Magic Workout and can’t figure out why they repeatedly get injured or continually getting slower, despite putting in more and more effort.

    Their Magic Workout isn’t more effort or speed. It’s the easy effort run with a heart rate cap. Over time, those easy miles allow your body to magically transform into a cardiovascular beast—and that is when the true magic can happen.

    (Dive deeper into the physiology of and my perspective on heart rate-based training here.)

  • How do I know if this is the right training plan for me?
    Because this is a RERUN plan, that means you have previously registered for the plan and now are looking to follow it again while accessing all the hands-on resources TLAM and Coach MK offer.

  • I want a PR. Will heart rate-based training get me one?
    It is totally possible. A PR is twofold: running consistently, and knowing how to race. We will help you do the former and teach you how to do the latter. The comment I—MK— get the most frequently from my runners who previously struggled through races is, “I never had to stop! I ran the whole way through!” That alone can lead to PRs.

    That said, the plan isn’t always the problem when it comes to a PR. Sticking to it is. If you run consistently and arrange your life so you can commit to the plan, I’m confident you will blow your mind on race day. It will be an experience unlike any other you’ve ever had.

    But if you look at the plan like a buffet and only pick the parts and runs you like or you continually find the day has ended yet again and you are out of time to run, you will still find a modicum of success. But a PR probably won’t happen. I’m not sure in those circumstances a PR could be expected on any plan. (Not being harsh; just being honest.)

    If you want proof of the beauty of low and slow consistency, look at me. I did not train through my third pregnancy, no running or cardio, NOTHING (I discovered ‘binge-watching’ and Sons of Anarchy…WORTH IT!) from September 2014-May 2015. I started a plan very much like the ones in the Train Like a Mother Club after my six-week post-partum appointment. I made it four weeks before I had a minor surgical procedure that left me prone in a bed until mid-July.

    My first easy run on July 28 was 14:15 pace. I cried knowing the 2014 NYC Marathon was 13 weeks away. I got back on the plan: five easy, effort runs of varying mileage weekly, no speedwork, but no excuses either. I was consistent. I ran 1:51 at the ZOOMA half-marathon in Colorado Springs in mid-October and a 22:38 5K the following weekend. Two weeks later, I ran 4:16 in the New York City Marathon, pacing a friend to a huge PR. I finished with lots of fuel left in the tank.

    To be sure, I have a wide cardiovascular base built on years of training smart, not hard. But still: I am living proof a #motherrunner (of three) can run slow and race fast.

  • I am constantly injured. Why will heart rate-based training help me stay healthy?
    Muscles have memory, but tendons and ligaments do not. I—MK— see runners going too fast all the time who swear to me, they, “feel FINE!” Perceived effort can be shaded so many ways; the heart rate cap will keep you honest and keep your easy effort days easy. This in turn will prevent you from letting those muscles that feel FINE push your tendons and ligaments beyond their breaking points, leaving you with a roaring case of plantar fasciitis, IT Band Syndrome, Achilles tendinitis, or shin splints.

    Heart rate-based training slows you down so that your tendons and ligaments have time to get up to speed; in addition, many of the short strength circuits you’ll do after your runs will encourage all the right kinds of running strength.

  • What are target races?
    Good question! Target races are races where we are expecting a critical mass of #motherrunners and TLAM coaches, so you’ll have both teammates and coaches to enhance your weekend! We’ll have a shake-out run, some kind of party-ish gathering, and cheering sections. They are a blast! We will put out a call early in the programs to identify people who will be at the Target Race, so if you need a roommate, we can help you out. (Don’t be shy about attending alone! Truly.)

    Please note: For target races, you are responsible for your own entry, travel, meals, etc. The only situation that doesn’t hold true is the AMR Retreat.

  • What heart rate monitor do you recommend?
    Coach MK and Dimity both love, love, love and use the Polar M400.

    Here’s a little more advice from Coach MK:
    Go for the low-hanging fruit. Translation: You might not need to run out and buy a super-expensive and fancy new watch.

    Did your current watch come with a strap that is sitting forgotten and unloved in a drawer? Grab it.

    Is your current watch heart-rate enabled but you didn’t buy the strap at the time because you didn’t think you needed it? Get the strap that goes with your watch.

    If you’re ready to upgrade your whole system, check out the price of the watch you want. Sometimes the stand-alone strap is pricey enough that it makes more sense to go ahead and upgrade.

    Don’t have a watch because you run with an iPhone? Look at the available GPS apps like Strava, MapMyRun and Runkeeper. All will sync with different heart rate straps, so check prices and pick the combo that works with your budget.

  • Do I need other equipment for this plan? 
    We have optional super short routines that involve a BOSU and resistance loops. While they are not mandatory, they are crazy helpful in building glute strength (BOSU) and hip stability (resistance loops)—two areas that are usually lacking in #motherrunners and are the root of many running injuries. If you don’t have access to or funds for a BOSU, don’t sweat it; resistance loops are adequate and are much more affordable. (You can also look for a used BOSU on craigslist, a used sporting good store or at garage sales.)

    We also recommend having a firm foam roller; the more dense it is, the better. (But we admit: It will be a little painful the first few sessions!) Our first choice is the TriggerPoint Grid X.

  • Do I have to do a bunch of calculations or complete a running test to figure out my optimal heart rate zones?
    No. Here’s why: When I—MK— started as a coach, I was handed a motley crew of 20 people who were at varying levels of fitness. Not a single one had a decent endurance base yet all were severely overtrained. I was floored. People running less than 15 miles per week shouldn’t be overtrained! Worse, they would absolutely kill themselves on our Tuesday night social (easy effort) runs and swear they weren’t failing the “Talk Test,” or being able to carry on a conversation while you run.

    A big believer in Lydiard’s rule that a well-coached athlete should never be injured, I knew I had to come up with a system that would work for everyone without alienating anyone.* I respect Phil Maffetone’s work and initially told everyone to use his formula (Heart Rate cap: 180-age, with a few exceptions) on their easy effort days.

    This failed spectacularly. Everyone bent the rule, so I set out to write a different rule. I researched all the data and theoretical reasoning behind most existing heart rate training programs, read up on studies of the existing endurance running population in North America, then looked at the success rates of my athletes with their Maffetone formula and reevaluated the verbiage around my ‘rules’ for the easy-effort run.

    The result was a 140 cap on heart rate for easy effort runs. Keeping your effort on or below 140 beats per minute is firmly aerobic territory for most of the population of non-elite endurance athletes and will increase the endurance base and running economy. (Dive deeper into the physiology of and my perspective on heart rate-based training here.)

    In an effort to make sure my runners do as little math as possible, and because perceived effort is not always an effective, we ALL wear heart rate monitors and use 140 as a cap for easy efforts. The cap comes off for other workouts—and there are plenty of times we pick up the pace—but keeping the easy efforts easy will transform your running.

    Exceptions to this rule are people under 20, over 60, and former competitive**/elite endurance athletes.

    [[*I’ve been the fat kid at track club more than once. I HATED it. I make a point to make sure everyone is treated equally and fairly at my group workouts, and have developed a system that ensures no runner is ever left behind our demoralized.]

    [[**By ‘competitive’, I mean, “someone who was ranked in the top 10% at the state level or nationally in track or cross country either in high school or college.]]

  • Does the registration fee include a race?

    No. The fee covers all the support you need for 24 weeks (nearly 6 months!) of heart rate-based training. That support includes an active Facebook page and Strava club, at least five exclusive podcasts, a Training Peaks Account, a stocked swag package (over $25!), and regular office hours where we can help you over speed bumps.

    All these tools will help you have an fulfilling training cycle and race, both physically and mentally. You will have camaraderie, commiseration, and community on a daily basis—and sometimes hourly, if that’s your thing.

    You can participate in the organized half-marathon of your choice; you can also choose to run a half-marathon on your own, if that works better for you.

  • Wait: So I have to pay for this Challenge and a marathon entry fee?
    Yep—and we’ve heard again and again it’s worth it. Staying committed and motivated during the days, weeks, and, yes, months of training can be ridiculously hard, especially if you’re new to heart-rate training. If you can do that—and these programs are all about accountability and inspiration—race day becomes a celebratory victory lap, not a slog full of self-doubt.

  • Can you please explain the shipping charges?
    Within a few weeks of registration, every participant in a Train Like a Mother program receives a stocked swag package with some of our favorite training essentials. Domestic #motherrunners are charged $7.00 for shipping; international #motherrunners are charged $15 for shipping. The Train Like a Mother tee and medal have no shipping charges associated with them.

  • What if I realize this isn’t the right training plan for me?
    We definitely want this to work into your life and your running lifestyle. You can email us within 2 weeks of starting the program and we will set you up with another plan or a credit for an upcoming challenge. We will not be able to issue a straight-up refund.

  • What if I get injured or really sick?
    With a smart training plan, doable strength training, and advice on foam rolling and other self-care, we’re going to do our best to keep you injury-free. That said, if you have an injury or illness that totally slays your training, let us know. We’ll work with you to get you a credit for an upcoming program.
