I too used my road bike for Longhorn and it worked out perfectly for me. I would agree with KSH, Longhorn is a great race and will be even better now that it is an official 70.3 race.

KSH, what did you not like about the PrairieMan bike course? Just curious. I wish I could do the full Longhorn again this year, but the timing isn't right. Will I be disappointed in the PrairieMan course? What was the run course like?
