2015 Mock Sprint Tri Results

I had some issues with my Garmin 910xt, but eventually I fixed the mock tri file. Woot! Next time, I'll disable all auto lap functionality before starting the tri, because apparently that's what interferes with the run data & corrupts the file.

Total moving time (not stopped @ stoplights): 112 minutes (1 hr, 52 minutes). Or more or less totally in line with most average beginner times, with a slightly better bike and a considerably worse run. Not at all unexpected.

* Mock Swim: 7:29. https://connect.garmin.com/modern/activity/715055281
T1: 7:26.https://connect.garmin.com/modern/activity/715055283 . I will do way better than this if I'm not DRIVING from the pool to my house for T1.
* Mock Bike: 47:49 https://connect.garmin.com/modern/activity/715055284
T2: 2:05 https://connect.garmin.com/modern/activity/715055285
* Mock Run: 47:07 https://connect.garmin.com/modern/activity/715055286 (This is the totally broken part)

Glad to have the data & compare it to my first super-sprint from last year:
* RCStake Swim leg I'm twice as fast (it was 300m 6x50m, not 700m): https://connect.garmin.com/modern/activity/560790985
* RCStake Bike leg 2MPH faster: https://connect.garmin.com/modern/activity/560790991
* RCStake run leg: OK, I was a little slower today than on the run leg last year. But the mock tri is nearly twice the length. https://connect.garmin.com/modern/activity/560790995 .

Observations:
* My 910xt is finally recognizing my swim strokes as freestyle instead of backstroke! This means my form work is starting to pay off. And those laps I did do backstroke are almost twice as slow as freestyle, which clearly tells me I need to avoid backstroking if at all possible; a slow freestyle is faster than my fastest backstroke!
* I blew up my legs on the uphill bike leg and didn't work nearly hard enough on the back half of the ride while mostly cruising dowhill. My calves cramped up on the first part of the run, probably from under-use on the second half of the bike ride.
* I need to learn to aero, or spend more time in the drops. I spent maybe 25% of my time (or less) in aero on my road bike. Sure, they are just little shorty aero bars, but nonetheless it was windy and I think it would have helped.
* Hydration & electrolytes were OK, but I think I'd do better with some timed nutrition: a little EFS electrolyte drink before the swim, a little on the bike, and my energy levels should stay a little more consistent on the run. More mental than physical, I think.
* Transitions were rough. Going to optimize them a bit for my first sprint in two weeks.
* Too much hotfoot & walking on the run. I should use my metatarsal pads on the bike ride and probably Vibrams instead of my clunky running shoes on the run. My turnover will be quicker, and for such a short duration on the run it should help avoid the hotfoot I often get on longer runs well over an hour.

Excited. Clearly I *can* finish the sprint tri in a reasonable amount of time, and I'm pretty certain there will be at least a few non-DNF people behind me at the end. Which is really all I can ask :-)
