Building running-specific fitness is like building a pyramid. You have to start with a wide, solid base that can support the demands of the structure as it grows higher and higher. The stronger and wider the foundation, the better your performances will be at the peak.
Without a stable base? The pyramid is going to collapse into the sand—or in your case, result in injury, burn out, sickness, or a performance plateau.
The most efficient way to build your own, never-gonna-break-down pyramid is to train in your own heart rate zones.

The majority of the runs in this program are in Zones 1-2, which helps you build a solid foundation of cardiovascular endurance and keep your risk of injury low.
Running by heart rate requires patience and persistence. You will likely run slower than you have in years, and your post-run, “I’m-a-b*d*ss” glow may not feel as intense as it usually does. (But make no mistake, you are STILL a b*d*ss!)
The thing to keep in mind is that that post-run, b*d*ss glow is likely from a Zone 3 effort, which leaves you prone to injury + stagnation. What’s more, that glow is temporary, and fleeting euphoric feelings are typically not worth the long-term drawbacks.
Often athletes abandon training in lower heart rate zones out of frustration or boredom—or because they just can’t bear one.more.slow.run—and move on to the higher zones for one of two reasons:
A) They get to maintain a nice clip and satisfy their inner competitive beast
OR
B) They believe that training harder will yield faster and stronger results.
A is true—it does feel good to run fast, but it doesn’t do anything for building endurance or warding off injury. And B? Simply not true. We—Coaches Jen + Liz— have trained athletes by heart rate for over twenty years, and have seen huge gains when they lean in, slow down, and trust the process.

After taking a year away from running I signed up for this program to ease me back in, and it was just what I needed. Being new to heart rate training, I appreciated the support of the coaches and the community. The heart rate tests make sure that your plan is tailored to your body and changes as your fitness improves. It gave me useful skills that I was able to carry over into a traditional half marathon plan after this one.

I wish there were more stars to give. This program and the support from the coaches, BAMRbassadors, and the other mother runners got me to the finish line faster than I ever have in the 10k (#fasterafterbaby). I heart heartrate training. I don’t think I will ever train using a traditional program again. Heartrate accounts for everything: training stress, life stress, weather, illness, and more.
If you are like me (read: will complete anything on a training calendar regardless of how you feel because the almighty training PDF told you to… You need this training plan. You run minutes not miles which is so liberating. You run to “hard” or “easy” for THAT day not under ideal conditions. I completed the intro, and, 10k plans so far, I’m in the middle of the half marathon plan, and will purchase the marathon plan next. “Don’t think just go” with this program ❤️

This progrsm really helped me back into running. Learning about zone 2 benefits me still a year after I started. Knowing that alternating fast a slow runs has brought me far. I can recommend this program highly. Yesterday I did zone 2 half marathon as a training run for fun. This program got me there.

I started running by Heart Rate back in 2018 and when AMR got new coaches, I decided I wanted a refresh so I signed up for this program to train for a Zooma 12k. The training plan was easy to follow with fun, different runs every week plus strength circuits that kept me strong. I was training in super hot, humid Florida and I found I was able to keep my heart rate in my target zone and work on running long and mentally focused as well as getting in speed work. I felt supported by my coaches the whole way. I PR’ed my race and even better, it was the first time that my husband and three year old daughter were at the finish line to cheer me on! I will continue to use training plans by AMR for the community and the expertise offered.

I was struggling with running consistently and wanted to get my groove back. I enjoyed the taste of heart rate training we got in Many Happy Miles and love Jen and Liz’s no-nonsense, practical coaching style, so I decided to give Heart & Sole a try. WOW WOW WOW this program is TOTALLY WORTH IT! It was just the boost I needed to fall in love with running all over again! I am now running much more consistently and STRONGER because of heart rate training. Looking forward to training for my first 13.1 in over 5 years using the half marathon plan in the spring! Thank you as always to AMR for putting out thoughtful, realistic, and flexible plans that work for even us back-of-the-pack folks!

After being a runner for many years, I decided to pursue a 10k running program around heart rate to challenge myself differently. I knew I always started off too fast when I ran and needed to change my technique. This program is great for forcing you to SLOW DOWN and focus (of course!) on your heart rate!
I found this program more mentally challenging than anything…when my body wanted to go faster or just run period (instead of walking), this program would say no based on my heart rate. There’s nothing wrong with this! But, just beware you might be challenged mentally through the process as much as physically. Also, if you’ve got long-covid issues with breathing or heart rate, are training in a high heat, or on very hilly courses these factors will highly influence your heart rate and if you’re running or walking at any given point. The program as a whole is great, but I just didn’t consider all the factors when I signed up as I should have.
The coaching guidance and variety of workouts throughout was fantastic! I did the Love the Run in 2020 and absolutely loved it as well. AMR has fantastic training plans!
