So --- I did my first 1/2 IM (ironman) of the season yesterday. here is a mini race report:
Wore the bikilas!! they were much easier to get on during transition than I think my KSO's would have been -i think mainly because the opening is much wider. was debating on which pair to race in up until race morning and setting up transition. The bikilas did well and weren't really all that wet considering it poured in the morning during setup and while waiting for the swim start. I had one small chafe spot on my left heel - but that's from some dirt/stone being stuck in there. but not bad at all, very mild. No other blisters or signs of chafing!
was having a strong first half of my run --- then I hit a water station that was out of water, and I was in need of taking my electrolyte pill (I use hammer nutrition's product called Endurolytes) and they said "we have HEED". so, i took it - before I realized that what I was drinking was actually gatorage (HEED has no color, its basically clear - and gatorade is a tell tale green/yellowish color...and the taste difference....WOAH, can't even begin to tell you!) anyhow, I had already swallowed some to take my endurolyte - and then spit the rest out. It was too late - what I had in my stomach was enough to upset it a few miles later. I was SO sick to my stomach that I had to stop eating my perpetuem and eventually stopped drinking water too!

SO not good. finished, but not happy with my time, nor being sick the last 5-6 miles of a 1/2 marathon - when I was just starting to get into a good rhythm and felt really strong! Needless to say I was VERY bummed out!
race directors swear that all they had on the course was HEED. Uh, I am wearing a team hammer top and hammer shorts and carrying hammer pill containers - i think that I know that gatorade is green and HEED is clear.
saw one other VFF runner there - its someone from my area that I actually know and he was wearing his blue bikilas!

got quite a few "go VFFs!!" from the non-VFFers too! my frien carl wore his VFF flows for the run in IM China - as well as Boston Marathon this year - which was very shortly after IM China.
One guy asked me "are they comfortable to run in" -- I said 'yeah, no problems so far!'
My take away from this race:
1- always look to make sure you know what you are drinking
2- carry some whole wheat pretzels with me in case of GI issues, as this has worked in the past for me.
3- just be glad that this was not at IM Lake Placid. this was a training race - a place to work out the kinks and dial in race day nutrition.
