Largest Road Races and Triathlons in Greater Houston?

What are the largest road races and triathlons in the greater Houston area on an annual basis?

There always seems to be a discussion from time to time as who has the largest event or not.

Well, guess what?  We're going to keep score.  And the only way to do so is by official timed finishers.

This first posting is going up on Tuesday afternoon, September 24 (a second update was made on October 2) and the total is now 219 races.  However, there are many, many more to capture from earlier in the year and I'll be updating this through the end of 2013.

Timer Legend:  CS - Cadence Sports, CT - Cajun Timing, FLS - Fastlane Services (Brian Muck), IAAP (San Antonio), NLT - No Limits Timing (Mike Hutcheson), RC - Richard Campbell, RF - Run Far (Raul Najera), RHT - Run Houston Timing (Jack McClintic), RW - Run Wild (Gary Mulvihill)

Note:  Relays, listed at the end of a line, are not counted as individuals and included in the totals.
