I am amazing at high-level training and at being a couch potato, but I basically fail at everything in between. At the height of my running career, I had 2 training cycles that consisted of 6 days of activity, 3 brick workouts (triathlon training), and 2 strength days, and I didn’t miss one day.
Tendon injuries can be incredibly frustrating. While you can have a lot of improvements quickly - a decrease in the amount of pain (less intense or severe), improved flexibility and strength, and better running - the pain can linger for quite awhile.
Back in the day, I was a fast runner. I have a distinct memory of going to Penn Relays as a junior, so excited to run the 4x400 (I was the anchor) and that morning I woke up with my period. At that point in my life I got my period every few months but most of my teammates hadn’t had their period in over a year! I wanted that. It was such a badge of honor and I was so embarrassed to be the only fast girl who got her period in season. Years later I learned that is called amenorrhea and that nothing about it is cool.
