Lately I’ve been doing a bunch of sprints and VO2 max efforts while helping my son train for XC racing.

Good for me, as it’s where I’m lacking.

Bad for me, because his 14 year old, 5’4 and 115# behind is now smoking me. First he started getting me on hill sprints, now he’s got me on the flats.

Last 30 second hill sprint I hit just below 1100w, he rode right away from me.

Yesterday we did a 4 min (for me) climb at full gas. I was pushing 340-350w, he put 30 seconds on me - put 10 seconds on his coach… out sprinted him at the top.
