One brother told the other one to race, so that way one of them would reach the castle gate in second place, and maybe he also told him "No cheating!" or something like that.

Another answer would be "Let's have a fun race, and whoever wins the fortune will share half of it with his brother. So if I win, I'll share the fortune with you, and vice-versa. Agreed?" Can't think of anything better, lol.
