Technical Data

The following data is derived from the Jack Daniels' VDOT Running Calculator at this link using "Advanced Features". It calculates the effect of temperature on a runner's running pace over a specified distance. Using a reference temperature of about 60 degrees (below this temperature has little effect on a runner's time), it can calculate the effect of higher temperatures on a runner's pace and time over a given distance.

5K Age Group Runner

Temperature (°F) Time (min) Pace (Min/Mile)
60°F 30:03 9:40
70°F 30:31 9:49
80°F 30:58 9:57
90°F 31:26 10:07
100°F 31:54 10:16

Testing of the ICED Cap has shown that running with ice lowers the effective temperature of a runner by about 20°F. If it is 80°F outside, the runner will perform as if it is 60°F. If it is 100°F, the runner will perform like it is 80°F.

As can be seen in the above data, a runner who normally completes a 5K in approximately 30 minutes can save about 17 seconds per mile for about a 55 second overall time savings. These figures will vary; heat affects every individual differently.

10K Age Group Runner- Advanced

Temperature (°F) Time (min) Pace (Min/Mile)
60°F 40:04 6:27
70°F 40:41 6:33
80°F 41:18 6:39
90°F 41:55 6:45
100°F 42:32 6:51

For this runner, the anticipated savings would be about 8 seconds per mile (or about 1 minute and 14 seconds for the whole race). Even if the runner slows down for a few seconds at an aid station, over a minute should still be saved due to the ICED Cap.

 

Half Marathon- Beginner Triathlete in Half Ironman*

Temperature (°F) Time (min) Pace (Min/Mile)
60°F 2:45:15 12:34
70°F 2:47:48 12:43
80°F 2:50:21 12:56
90°F 2:52:54 13:06
100°F 2:55:26 13:19

The above runner saves about 22 seconds per mile (about 5 minutes total).

Marathon- Triathlete in Ironman*

Temperature (°F) Time (min) Pace (Min/Mile)
60°F 3:10:18 7:16
70°F 3:13:13 7:23
80°F 3:16:10 7:29
90°F 3:19:05 7:36
100°F 3:22:01 7:42

*In which ice is provided at aid stations.

This indicates a pace savings of about 13 seconds per mile (about 6 full minutes); a substantial improvement from products frequently purchased by runners and triathletes to reduce their times. For instance, an aerodynamic water bottle is available for sale at a $90 cost. Reviews show that this water bottle only saves about 10 seconds in a full triathlon.
