I've got my T1 transition down to 30 Seconds (at the bike - not
including run from swim or to transition exit - obviously those are
per-race variables). So this includes dropping swim equipment and wet
suit, putting on helmet, shoes, sunglasses.
For me that's about 15-25 seconds faster on a half mile swim+T1 VS not
wearing a wetsuit - (and a hell of a lot warmer and less fatiguing).
I have two tricks for wetsuits.
First is to get water in the suit and let it drain out. I do this
before the race starts by pulling my shoulder strap (I have a farmer
john) to the side and then simply walk to shore. This frees the suit
from your skin. On exit from the swim I do the same thing. Just pull
suit where it meets my arm pit to *scoop* up some water. As you run
out of the lake(pond/ocean) gravity will force the water through your
legs and agin release the suit from your skin.
Second trick is at your transition area. Pull the top of the suit down
as far as it will - turning the suit inside out. Do not try to slide
your legs out. I did that all last year and it does not work (at least
not quickly). Instead, use just your legs to get the suit off. This
basically requires about 4 steps marching in place. The suite will be
completely inside out when you're done.
Absolutely take your cap and goggles off when you exit the water (do as
much multi-tasking as you can manage well). Fold the top of your
wetsuit down to your waist as well.
Regarding shoes - you have to practice to see what makes more sense.
I've practiced numerous times with shoes pre-mounted and have yet to
make a faster transition than if I leave the shoes off the bike. You
have to be careful, but if your shoes have enough traction you can
still do the run and jump. The run and jump will save you time - about
5-7 seconds - than trying to clip in and go.
