Wattage jump?

This is cool - the day after wente I did the Sunday club ride and set a new PR up Old La Honda -- 347 watts average for 18:30. And the time would have been lower had I not been carrying a bunch of water, jacket, etc. Also set a new 10 minute best of 355.

Of course, it also means I didn't push myself hard enough at the race yesterday: if I had my legs would be dead and I would have been at home watching Hulu instead of charging with the club riders out to the coast.
