I was wondering if there were relay triathlons. I'm a strong rider and swimmer but too heavy for lengthy runs. I've been considering a sprint tri (my first one) but the training would conflict with at lease one multi-day charity ride I'm doing in September. I really like the cross training aspect of tris but don't want to burn myself out. I feel that my conditioning would be adequate for the biking part and I wouldn't risk fatiquing myself if I only had to concentrate on that aspect of an event. Do they have events where a team of 2 or 3 compete in a relay-type race?
