For those of you who train with hr monitors, do you use them with you race?
My two thoughts are:
Definitely - that way I should prevent going out too hard early in the race.
or
definitely not - If I know how hard I am actually running, instead of the boost from the race mojo, I'll cause myself to either feel more fatigued or slow down more than I would otherwise.
Thoughts? |

First of all Racing HR's and Training HR's are completely different. They don't translate.
This is my first year actually racing with one but I have not used it to adjust pace or as you suggested to make sure I don't go out too fast.
I still race on feel.
However, if you're a HR zone trainer you might want to use it while racing.
FWIW, I tried to questimate what my half marathon HR would be prior to a race last month based on a 8 mile tempo run HR at close to HM pace. I was off by almost 10 BPM, i.e. I thought it would be around 170 but it was actually around 180. If I would have used my HRM to make me run at 170 I would have ran too slow considering my times that day.
That was all the convincing I needed to keep racing on feel as I always have.
But if you don't have a lot of racing experience it might be worth wearing just to keep an eye on things. |

| I don't, maybe I should. I have heard of people who do, and it works well for them. |

| Yes, I do, on marathons/ultras. It's an almost perfect predictor of how the last part of the race will go. If I am above my target zone early, then I will bonk sometime between 18-22. It's especially helpful early in the race when I feel energetic and am tempted to go out too fast. Also on shorter races (10k-HM) which I use as training runs. I don't use it so much on training runs any more, though, except strict aerobic runs. |

That is actually one of my bigger problems in using the hr monitor in the race. I don't know what my hr should be for the race. I've only raced without it.
Why did you decide to start using it?

| I would wear it but not pay any attention to it. Just race by feel the first couple times and then look at the data afterwards (I assume you have one where you can do that) to see what it tells you. |

...
I should have qualified my post--in races I only use it for guidance on marathons or longer. On shorter races I go by feel, unless I'm using the race as a training run, then I use it as a indicator of effort and not a pacer.
Here's the thing--if you run slowly (purely aerobic) you can go just about forever. That's how people can run 100-milers. If you run faster you are burning glycogen, which is limited and will eventually run out and you will hit "the wall". The faster you run, the faster you burn glycogen. So the key is to run just fast enough so that the glycogen lasts 26.2 miles (or whatever). That's where the heart rate monitor comes in. For me, if I'm in the mid-160's early in the race, I know I'm going to bonk if I don't get it back down. It took a lot of miles and races to figure out my ideal zone.
At shorter distances glycogen depletion is not a factor. |

I have always used mine as a stop watch anyway but I find it useful to stop me getting carried away at the start although over the years I look at it less and less.
Last weekend I did a half and it was seriously hot ( 31C at the end in the car park ) the course was hilly so I decided to run at a lower HR than usual and "rest" before the hills, it worked for me and I don't think I could have gone any quicker. Anyway Half's are long and it gives you something to look at. |

In theory, that's great. I doubt that I'd be able to keep myself from looking! |

Late getting to this...I probably started wearing it just to see where my race HR is at different distances. |

In a short race I doubt there is any benefit.
When I run marathons I use it to monitor where I am relative to my Lactate Threshold. If I am going out over that HR then I may be in trouble later on.
In the latter 1/3 of the race I go more by feel - at that point if Lactate is building up I don't care because I will be done with the race.
For those that say that training and race HR are not equivalent, I would argue for something like Lactate threshold, it is in general not going to change much.

| I have always worked out with a heart rate monitor even if I am cross training; at first I had just a basic polar monitor and calculated zones, then I went to Karnovan zones by subtracting your resting heart rate. About 3 years ago, I bought a RS200D polar heart rate monitor, and its taken a couple of years to figure it out, but essentially, it has a feature called OwnZone that is worth the cost of the watch itself, in addition, it has a built in VO2max tester. Also, it has a pod that I place on my foot that tells me pace that can be switched between km and miles. At last 1/2, I knew that once heart rate goes over 160 that I won't be able to sustain for long time, and I kept pace at 159 the whole race, at the end I had some left in the tank for a nice sprint the last mile and set a PR even starting out and being blocked the whole race. Tempo runs are my favorite with a HR monitor with all that said! |
