Evenepoel doesn’t look where he’s going very much. Doing that on open roads is dangerous IMO.
Being able te see what’s ahead is a must for your tt position but with TR you’re either on the trainer or in a race. So I would definitely also train your head down position for the occasion that you are able to use it.
I make my position so that is can see about 15 meters up the road and pick up my head to see what’s up head every few seconds
