Reliable calculator to estimate TT speed/power avg.

[LouisN]

I completed my first TT bike build last weekend .
I plan on doing an upcoming event (early may) and would like to prepare specifically for it. I'm setting power avg. targets for the season, but for a specific event, with many variables, I would like to be able to put some specific numbers on the effort.
How do you guys do your specific prep for a TT ?
I have the course on map, with the elevation.

Take a look at the bestbikesplit. I think it is just for this purpose.
