Re: Figuring out 2x20 wattage

I did it inside on a trainer and don't feel like i could have gone any harder (maybe if i was better rested). Should i just try different wattages? I don't want to have to do "trial and error" if it isn't needed. If it must be trial and error is there any ballpark figure someone could give me (285? 300?) Thanks for the help, and this time of the year about 2 months before my first race (cat 5) how many times a week should i be doing 2x20's? Thanks for the help.
Just go out and ride your bike and try it.
Once you find you can repeat some wattage comfortably, slowly try increasing the wattage you can do repeatedly the same way you would increase the load for any type of typical training plan over weeks and months. And if you find you can't keep it up at whatever you picked, next time try a little lower.
The hard part is finding a place to do it safely outside.
We get power meters to guide us, not rule us, don't obsess so much over getting the *exact* numbers the first time out. One has to be able to ride without watching the display all the time and when the equipment fails...
