10-10-100 (10-mile run, 10-mile bike, 100 laps in the pool) is a weekly training routine I created. At times, it’s the thing I look forward to most each week. Some days I dread it, especially this one right after a half marathon. I love seeing myself get faster and stronger every week, and at the end of the day, it doesn’t matter if I feel good or not—it just feels good to keep showing up.
