Marble Falls Triathlon

I'm preparing for the Marble Falls triathlon.  It should be an interesting race.  It's a 1K swim, 23 mile bike through the hill country, and a 4.4 mile run.  Not sure how/why they came up with this distance. But, I'm looking forward to it.  Looking to build on the momentum I had from the Lake Pflugerville Triathlon.  I just registered and the race is Sunday so I'm thinking it might be a small race.  I keep stepping up the distance to each one is a challenge.  Looking forward to it.
