Hollow, You've raised an question that has been crossing my mind of late. Next year I'm gonna do my first triathlon (400m, 23k, 5k) along with some colleagues. One colleague is both a good runner and a fair swimmer. Looking forward I expect my colleague to be out the pool some 5 mins before me but I expect to catch and pass him on the the bike finishing some 5 mins + ahead which leaves the run. He'll do the run in under 25mins I'll be 30mins +.
Could be a close finish!
