Nation,
If a race is all together at the finish, what's the best way to help out a teammate who has no sprint? All I can think of is to get on the front for the last 3-5 minutes or so and try to drill it all the way to the finish. A sprinter will still win but at least that will weed out the tired sprinters and minimize the number of non-sprinters who pass him. Or maybe try to slingshot him off the front with 1-2k to go? Except that seems just as likely to do nothing useful, if he can't get separation from the field (see the part where he has no sprint, above). ???
