Dallas has a great triathlon scene - lots of lakes in the metro area make for a lot of different venues for triathlons. Right now, North Texas doesn't have any Ironman-branded races, but the Toyota US Championship in October is the finishing race for the Lifetime Fitness triathlon series!

The PrairieMan half iron distance triathlon is the longest triathlon in DFW - for iron-distance racing, do Ironman Texas in May in The Woodlands (Houston), or Redman in September in Oklahoma City.

Training in Dallas is actually pretty easy - there are a lot of clubs, training groups, and races. There's also a great calendar of bicycle charity rides and local road runs that can help add some competition to a long training year.
