Tires/inserts versus weight
Usually, I use molded inserts, but I would like to try out some sponge-types. But I've read that they can have heat-problems at the end of a race.
The temperatures on the tracks I race on, vary from 0 degree celsius to 25 (32-77 deg. F)
During races, I only run for 5 minutes per. session with 30-60 minute pauses inbetween. During practise, I run for around 8 minutes per session, and often only with 10 minutes pauses.
Are sponge inserts proper for these conditions?
