Heart Rate Moniter Question

If it is the HRM that came with your 910xt you can swim in it. I do it in all my tri's

It is the one that came with it. Thanks! I was 95% sure it'd be OK, but wanted to make absolutely sure.

Have never had an issue with wearing HR monitor under my singlet alone or with a wetsuit.

That said, don't be a slave to the numbers on your watch during the race. Great tool to make sure that you are not burning matches too early in the race (especially one that distance) but remember to listen to your body and how it feels.

Develop your race strategy and make adaptions on race day ... e.g. use your Garmin to pace you through the first 1/2 of the run and then run by RPE after that.

I used to be a slave to the numbers on my Garmin and my HR number. Had some good results but also think that I held myself back somewhat through fear of running out of gas before the finish line. It wasn't until that I realized that almost all of my PR's came during times that my watch malfunctioned (charging issue) or I forgot my HR strap.

Good luck on your race. Sounds like you have have been training for it ...enjoy your day!

Thanks for the great advice everyone! I've got a heart rate I'm shooting for on the bike, but it's not set in stone. I figure if I come out of the swim feeling pretty gassed, I'll back off for the first quarter to third of the race and slowly ramp up to my target heart rate. Likewise, if I'm feeling strong in the last third to quarter of the bike, I'll likely up the heart rate to get a faster time.

The run will be done almost exclusively on RPE - I don't even have a data field on my watch for HR on the run. The water stops/aid stations are spaced at every 1.5 miles on the run, and I'm planning on walking through every one. I've got a solid run/walk plan in mind that has worked well for me in training - run 1 mile, walk 1/10, run to the water stop at 1.5 miles, walk 1/10, run 1 mile, walk 1/10, run to the water stop at 3 miles, walk 1/10, etc. That said, even though it's worked well in training, I'm not married to it and will walk more if I feel I need it. I'm not necessarily expecting but I'm thinking it's very possible that the run to the first water stop might look more like run 1/2 mile, walk 1/10, run 1/2, walk 1/10, run to the water stop. I'm OK with this as I know from bricks and Sprints that it takes me close to a mile to get my running legs underneath me, so I'm ok with walking more in the first 1.5 miles. I'm hoping that if that happens I can get back to plan after the first water stop, but if I feel I need to I'll drop my runs to 1/2 mile for the entire race.

Again, thanks for the advice and support! I'm getting very excited but also very nervous about this race and just wish it'd hurry up and get here.

I think that's precisely why people use HRM & power meters because their body might feel great despite the fact they're going harder than they should, your body lets you know you went too hard when it's too late. Case in point a 70.3 I did last year, I wasn't using a HRM or PM, just relying on my speedo and "how I felt". Was really comfortable at 36km/hr, felt like I could ride like that all day, until I got to 80kms and then I suddenly went from feeling as fresh as a daisy to very flat and devoid of energy. Like a switch was flicked. And that was me done. The run leg was a struggle from the first 1km. If I'd had a HRM it would have told me I was going too hard. There must be thousands of people who have done similar things.

Do you wear the heart rate monitor and strap under the wetsuit, or just the strap and snap on the HR monitor in T1?

Trying to learn from your thread, partner. Best of luck. 70.3 for me in 2016.

Put on the whole thing under my tri kit, under my wetsuit.

All I gotta do is peel off the wetsuit, put on my bike shoes and helmet+glasses ( or in races where I can have the shoes attached to the bike, i just put on the helmet+glasses )

Cool. Thanks for the advice.
