I had a lot of problems with the water temp in my attempt at IMAZ 2011 with 61 degree water temp. The practice swim Sat before race day it was okay but most of us were in the water less than an hour. In the race I got only about 2 miles in before my body just shut down and I was in trouble with hypothermia. What recommendations do you guys have besides getting faster? I hope to get my swim time down under 2 hours for next years attempt but what else can I do?
I have done shorter swims (Olympic) in water below 59 degrees but I was in the water for only less than an hour.
Yes I wore a neoprene cap under the race cap and I wear surfer skin tight shirts under wetsuit but I have found some a bit thicker shirts from Quick Silver.
I was going to tell you what Ric said--both extra pieces really help--I have trouble with cold water also. Another thing--leading up to a race in cold water---go do as many practice swims in cold water as possible--you body does adapt to it. (Learned this from my friend that swam the English Channel 2 years ago--14 hrs in 60 degree water NO WETSUIT)
Good idea, I had also done a few open water practice swims in a mountain lake in Feb and March. I need more practice I guess and more Masters swim coaching on my stroke to get faster for longer swims so I stay in the water less than 2 hours for the IM swim.
I would not make it anywhere near 2hrs even with all the stuff--I have trouble in water under 60 degrees and I'm only in there for a little over an hour -- I'd be DNF'ing if I had to be in there much longer. I usually start shivering somewhere around 50-55 minutes.
I have done IMAZ the last two years and I agree with Ric andTom. Use a neoprene cap, practice in cold water or at least sit in a cold bath tub a couple of times a week. I also wear booties when the temp is below 65 degrees.
Best of luck.
Does it help condition your body to the cold water by swimming in unheated pool with no wet-suit in early season or do you need the wet-suit in cold water to really teach your body how to deal with water around 60 degrees?
I would guess either would be fine
May not be an issue, but make sure your wetsuit seals well and is tight (not too big). As I leaned up I had water flowing in and out the entire time during an OWS event, I ended up with hypothermia that took a couple of days to recover from. Wetsuit was too big and I could feel the water running down the back of my neck.
Two other things: One - try ear plugs to help reduce warmth from leaving your body. Two - Read an article Gale Bernhardt wrote on Active.com regarding: Acclimating Your Body to Cold Water - Google it and I believe you may find it helpful
Thanks, I can try the ear plugs in Olympic OW race Sunday at Tempe Town Lake in Marquee Triathlon. I know you should not experiment on race day but I have used ear plugs in my Masters swims in a pool several times before and once in OW but not when it was cold.
Good luck, let me know if it helps
