The race pace calculator from Runner's World seems pretty accurate. I entered my 5K times from before my half marathon last fall, and it was right around where I finished my half. Had I not stopped for the port-o-potty, I would have finished a few minutes earlier ;).
BTW, I'm from the Chicago area, too!

Yeah, I'm definitely not counting on hitting this exact pace or anything, especially since my current 5k time is now, when it's nice and cold, and the half will be in October, when who knows what the weather will be like. (I'm in Chicago.) Just wondering if the predictor was at least vaguely accurate so I could have a rough idea. And obviously, as I train and run longer distances, I'll get a much better idea.

They seems pretty on par for me up to the half marathon distance, but remember there are so many factors that influence our race performance--temp, humidity, sleep, nutrition, hydration, etc, that I think we must be careful using this as the benchmark. Practice half-marathon pacing is important. Below is a link to an article that may help.
For me, the predicted time is something to base my training for that race on. It can be very useful. But it is tough to achieve. It is a hard effort on an weather perfect day when my body is fully rested and feeling awesome.
If it is hot or humid, one's heart rate rises and one's pace suffers.

I've been running for about nine months now, and have run several 5Ks. I just registered for my first half-marathon, which will be in October. The registration form asked for my expected finish time, so I used a pace predictor ( www.runnersworld.com/tools/race-time s- predictor ). I'm just wondering if those predictors tend to be fairly accurate or not. Any feedback? (My 5k time, btw, ranges from 30:41 to 32:31, and the predictor gave me a time just under 2:30:00.)
