Low body weight is key to success in running, cycling, climbing, cross country skiing and other aerobic events. It is less important for swimming as long as you can maintain a good body position -which I postulate is largely a matter of body type.
Since I use this blog to keep track of my workouts, here is my update. I haven't done any since May 7 so this may be a bit long.
On Sat, May 8 I rode 25 miles with Alistair.
On May 9, I rested and watched the Berkeley Hills Road Race.
On Monday I ran 6.5 miles in the hills, in the rain.
On Tuesday I ran 8.6 miles to Montclair and back.
On Wednesday I rode for 1.5 hours.
On Thursday I once again ran 8.6 but it did not go so well this time around.
On Friday I rode the Bear's loop with Pig Farm Hill for a total of 20 miles.
Then on Saturday we went to Grass Valley for the mountain bike league state championships. I rode 7 miles with Annelise on the course.
On Sunday I rode some with Annelise and we went to Sacramento to see the finish of stage 1 of the Tour of California.
Monday was another rainy day and I rode 1:03 on rollers, including 20 minutes at over 325W.
On Tuesday I flew to Boston and swam in the pool for about 1 mile.
On Wednesday I rode 45 min on a stationary bike, and then ran 1 mile at 9 mph on the treadmill.
On Thursday I swam 100 laps in the pool -probably a bit less than a mile.
On Friday I rode the Bears loop plus Pig Farm hill.
