Most think base period you go easy and build up your distance/time. That is partly true but it should include working on your form and some speed workouts. Include cadence as a way to improve your form for biking and running. The past couple weeks, I have been running with metronome to work on my cadence. Saturday, I ran the April Fools 4 mile race which proved fruitful working on the cadence. My leg turnover felt good and pace improve by 80 seconds. So don’t forget your form and cadence on your next run/bike workout.
