A happy runner is a fast runner.
Stack is a completely customizable running log built around this idea. For many runners, standardized training approaches lead to burnout, injury, stagnant results, and resentment. That was the case for me, so I changed how I approach running. The result was tremendous strides in performance, truly enjoying every run, and an overall happier life. I bottled this up and created Stack.
FLEXIBILITY AND CUSTOMIZATION
You know your body better than anyone, and Stack honors this by allowing your training plan to be changed at a moment’s notice. Stack also lets you focus only on the stats that matter to you or add your own data points as needed!
RACE PERFORMANCE > FINISH TIMES
Having a great race is one of the best feelings in the world. Many of us constantly trying to replicate this euphoria. Stack makes this easier with Race Reflections. Stack automatically consolidates the three weeks leading up to your race and adds this information to your reflection, complete with all the details you need to optimize your pre-race routine.
RUN FOR FUN
When you run for fun, your body is more willing to make adaptations and improvements. Without pressure, you listen to your body. You’ll know when to run hard, when to run easy, when to call it quits, and how to recover faster. Stack makes running fun by letting you focus on what matters most to you!

Run Happy, Run Fast!
