PB great.
I think that this is where a lot of SUP contests will head. Short course SPRINTER 38 racing.

I have been trying to get some interest in this type of course for a little while now in my town. I have just had to wait for the SUP numbers to grow to a size of greater that 3.
I reckon it would be a great spectator and participant sport. Heats of 6, over a 500mtr course, round robin so everyone gets a couple of goes, short heat times.
Best of all every SUP rider can look over the course and think I can do that.
Weight for age handicaps, board size limited heats, 12'6, 14', 16'.
Two heats in the water at the same time, when the preceding heat is halfway down the course, start the next heat.
