high heart rate but low Z in run, HIM

 So in the Calgary 70.3 last weekend, I nailed the bike to the wall. 27 min PB, my Z3 target was 140W and I only got to Z2 121 - and my IF was .756. So I didn't overcook it.

However, I only took in one 20 oz bottle of gatorade (I usually take 2) bc I wasn't thirsty and I didn't want to stop to pee again. 

On the run, my HR kept jumping into Z5 when I was running a Z2 pace. I guessed this was because I was dehydrated. Is this correct?

with thanks

  • Yes...you were dehydrated. In general, staying as hydrated as you can is a very, very good thing, not withstanding stopping to pee. I prefer to drink ~2 bottles per hour of water/sportsdrink, a little less if the temps are cooler, and if that means I gots to go all the time, so be it. The alternative (slowing down, massive cramping, etc) is much worse.

  • two bottles an hour - my god you must go like a race horse! okay. more water it is! Thanks Rich!
  • 2 bottles an hour VS 1 bottle for 2.5 hours. I did something similar to you in LP and almost lost my day as well...the fluids are just as important as the impressive watts you see.
  • Really?? Thanks! Man I am so hazard about my bike. Muskoka is harder, but riding smart made riding easy!
  • Coach Patrick, just listened to the podcast about your IMLP. Two iv bags, impressive. Okay I get it drink drink drink!!
  • Real man woulda dropped his own central line. Just sayin. JK Coach congrats again!
  • BTW FWIW I am a big guy 6' ~200lbs and was having big problems managing lytes on the bike. After tweaking all Outseason and learning about some dumbass things I was doing re: solid foods before/during a big race, I have dialed it in as follows: nothing but liquid calories after 5pm night before race. Gu and Gatorade morning before IM swim. Once in the bike, watch beeps q15m take mouthful of Infinit off 3x concentrated bottle and chase with several mouthfuls of water = need new h2o bottle every aid station = approx 2 bottles per hour (a little more as I often took 2 bottles). Every half hour pop one Succeed S-cap the entire day from the bike onwards. Switched to oncourse Perform and h20 every aid station on run ad continued the s-caps. At The Line switched to Coke and chicken broth which is like crack and rocket fuel combined at that point of race. I made copious urine on the bike and run, and felt better after the race than any open marathon I've ever done. Feels very good to have at least SOMETHING dialed in that works and that I don't have to worry about. Now just need to learn how to swim and ride a bike. image. Hopefully this helps someone. Forgot what thread I'm responding to because can't see it on my iPhone!
  • Jane - At IMCDA I drank too much and had to stop to pee way too many times, but I felt good the whole way. On the bike, I drank a bottle of H2O between each aid station plus had a 3x concentrated bottle of Infinit that I sipped 1/3 of per hour. Got another 3x bottle of Infinit at BSN. Temp on the bike was in the 50s at the start, warming up to the low 70s F by mid-day.  I was drinking like it was the hot, humid Chicago summer.  I stopped 8 times on the bike to pee, but my legs and gut were fine.  On the run, I drank 2 cups of H2O at each aid station, grabbed a cup of ice to suck/chew on between aid stations and had more Infinit on my fuel belt.   Took 1 Scap salt pill at start of run and another after 13 miles. Again, had to stop to pee way too many times (9 times).  So while I was giving up some serious time stopping, I was well hydrated and able to run well.  I was even able to speed up at the end of the race and my last 10k run split was my fastest 10k of the race by over 8 minutes.  Result - I pass several hundred people in the last 6 miles.  Overall on the run, I improved my AG placement from 41st at end of bike to16th at end of the run.  Moral of story - if you are a good runner (and I recall from your Dec OS posts that you are) you want to be really well hydrated going into and during the run so you can maximize your run strength.  So drink more, stop for a pee, and then run down all the people who didn't drink enough. 

    Hope this helps.

  • At Racine 70.3 it was 94 degrees and I did not drink enough...only 2 bottles of water on the bike. However, I hydrated massively the 2 days prior to the race and downed 2 bottles of Gatorade in the 3 hours prior to the start. All the pre-hydration probably saved me big-time. I also pounded a whole bottle of Gatorade coming out of T2 that I think that made a huge difference in setting me up for a good run. Because once I started running I had a little styrofoam cup of water at every other aid station and that was it.

    As for losing time peeing, I totally hear you. About 6-7 miles into the bike at Racine I felt like I had to go, but I didn't want to waste time so I held it as long as I could. Eventually I was so uncomfortable that I decided I'd rather lose the time then be miserable for the rest of the race. I considered not stopping but I also find the concept of pissing myself to be pretty unpleasant. When I stopped I hit the lap button to track the time cost. The pee break was 2:31 of averaging 9.3mph. So I probably lost a minute and a half. That sucks. But I felt so much better afterwards that it was worth it. I'm not sure how you can control the amount of urination you'll need to do, but I wouldn't trade control for sufficient hydration or comfort. And I'm not yet ready to pee "en route" (and probably will never be).
  • Wow. That's a lot of liquid.

    I was good with hydration going into and out of the swim (one trip to the port a loo and in my wetsuit- and that was needed it was so cold)

    After the swim I peed en place in transition. Gallons. So I was well hydrated, but on reflection, I wonder if this is a DQ violation? I would expect it is. Warmed me up but it was gross.

    I can't pee on a bike either. I think women's physiology is all wrong. Plus it's weird!

    Any women able to pee while biking?
  • Rich, you said you drink 2 bottles of water/sports drink per hour on the bike. Do you concentrate a bottle as well? Do you get all of your calories from the two sports drinks? What makes you decide one thing versus the other?
