The American triple T is the only team tri tour in the US that i know of. It consists of 4 races over 3 days in the mountains of southern Ohio.
Friday afternoon you race the prologue- 250m swim/5mi bike/1 mi run
Saturday morning you race an olympic distance 1500m swim/40k bike/6.5mi run
Saturday afternoon you race another olympic with the bike first 40k bike/1500m swim/6.5mi run
Sunday morning you race the half ironman 2000m swim/56mi bike/13.1mi run.
All of this is done on some of the hilliest roads in the area.
All racers were the same jersey given out as part of the race package.
You can race the weekend solo or as a team (team mates complete the race as a team time trial rather than a relay).
All races are started in TT fashion with athletes starting every 5 sec or so.
Two races already 'under the belt'.
By this point in the weekend, no one is excited to be starting another race.
Race about to start, May 2009
The swim start.
A swimmer pauses to think about the race to come.
The first two athletes start the Half Ironman.
One of the first swimmers to head out, the water is much warmer this year (last year it was sitting on 55 degrees).
