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. Thanks, but no. 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.

In these weird Covid times it has been wonderful to sense community through AMR and to work towards a goal. I’m a beginner marathoner and am using the heart rate method of heart and sole. It has made me look at running differently- time and HR rather than distance and pace. The program has good variety of kinds of runs and strength. The Ask the Coach Monday’s are helpful- I tend to read all the questions others ask and learn from others. I like that there is weekly supplemental material in an email as well as the podcasts to complement. I am learning so much about my fitness and mental as well as physical stamina. As always, the BAMRs on the journey make it feel like I’m not alone on both the hard days and the days that feel like progress is happening.

I signed up for this program with a solid base but minimal knowledge of training by heart rate. Being an analytical person by nature, I was intrigued by the idea of applying formulae to improve my running. I already trusted Coach Liz and Coach Jen from Love the Run programs. I committed to going all-in to see how heart rate training would work for me.
I stuck closely to the plan for all 20 weeks (only missing 2 or 3 workouts) and – despite racking up weekly mileage that I hadn’t attempted in many years in the peak weeks – I was injury-free and felt like the plan gave my body adequate time to recover throughout. It took a lot of patience and mental work, especially in the first couple months, to get comfortable running slower on easy runs. Slowly but surely, I got more confident in how my heart rate zones felt so I could stop relying fully on my watch. I got much better at programming workouts to execute the intervals and progression runs, which I found challenging and confidence-building. I regularly asked questions on Ask the Coach Mondays and learned a lot from the coaches and from my fellow BAMRs. Thanks to the training plan and guidance, I felt mentally and physically prepared to execute my race plan and crossed the finish line feeling immensely proud of myself.
The downsides of this plan were minimal in my experience. I have to admit that I dreaded every single heart rate test (though it was good practice for being out of my comfort zone). I initally missed the glow from higher intensity runs but, by the end, I learned to love sexy pace runs as much as testing my speedier gears. Some workouts, it was hard to look away from my watch so a bit less zen while learning what my zones and goal paces felt like.
I’d 100% recommend this plan to a friend and hope to sign up for the Half Marathon or Level II plans in the future.

I loved this program! It does take time to get used to the zones and I didn’t enjoy the HR tests, but it all felt worth it. There’s so much support from the coaches and the group which is wonderful. I was able to complete almost every scheduled workout for 20 weeks without injury!
Also, I love that workouts are by time, not distance, which is so practical for busy women like us!

This is the third time I have done a heart rate based plan with these coaches but it will not be the last! I love the structure, the chance to use something besides pace and distance for progress, and the variety of workouts. Even when I am not on a specific Heart and Soul plan I still follow the principles because it means I feel good and so far have kept the injuries at bay. Having the weekly ask the coach and the chance for one on one office hours increases the ability to make the plan work for you.
