Weather and Racing

Post by Tinman » Wed Mar 02, 2011 9:58 am

A topic to think / discuss: Weather and it's relationship to Performance.

I am reminded of how the weather influences race-times. Two runners I coach flew to the famed Gasparilla 15km road-race in Florida this past weekend. Unfortunately the temperature was in the 70's and humidity about 80%, which brings about a heat index of roughly 80. As shown in my chart- see Tinman Tools on the home page for the chart - performance loss is about 3% at a heat index of 80. As runners, we are hard on ourselves - we expect good results from the hard work we put in - so it's natural for us to be disappointed when a time is slower than expected. But, using the Heat Index Chart I provided one can figure out just how much weather truly effected performance, and the adjustments provide accurate information about the relationship between training efforts and race-performance. I offer this post as a way of keeping people from beating themselves up for results that don't meet expectations. Take a moment to think about your weather and race-times. Often people are surprised, for example, at how much faster they run in the autumn, once the temps lower in the 60's and 50's, which is optimal.

Take care,

I live in Florida and ran a 5k this past weekend under similar conditions.

While fighting an upper-respiratory infection, on antibiotics and sinus medication, having missed three training sessions prior to the race, AND the course having three long rolling hills (unheard of down here) I came within 23 seconds of my PB.

I can only wonder what ideal conditions could have brought.
