First sprint tri of the year is on tap for Sun. Since I'm not polar bear gru, I'm not sure how riding a bike soaking wet in 45 degree weather will work out for me. The event planner had to change the run course and the new route is an abortion in the making. 800 people on a double out and back loop with a portion of it single track. :trainwreck:
I did a sprint last fall where the air temp was 38 at the horn. Things I wished I had done for the bike: heated the water in my water bottle I use to spray the sand off my feet (I ride sockless and my already very cold feet were made colder). Somehow covered the vents in my shoes (wet feet + lots of cold airflow meant I could not feel my feet fully until about mile 1 on the run). Applied some kind of anti-fog to my glasses (as my body warmed, the wet cold on me fogged up my glasses quite badly). Finally, I could have used arm warmers. I was afraid, because I could not feel my hands, that I'd lose the grip on my bars and spill.To warm your feet at T1, if you use a bottle to spray off your feet, heat water at home and put it in a thermos. Transfer the water to the bottle right before they close transition. I also saw a few folks with tub put hot water in there (but the air would likely cool it too much to matter. If you have footies for your shoes and can get them on fast and clipped in, I'd think about these.
All in all, I'd skip the arm warmers as they'll add transition time, but would try to find a way to get your feet warmer. For you, a sprint bike can't take but 30 to 40 minutes. Be cold on the bike and warmer on the run. Have a sleeved running shirt out and ready for T2 (with a WIDE collar). You can run and put on a shirt, but can't put it on, on the bike.
:jealous: you get to be racing so soon & hope this helps!!
