Hello everyone,
I have the Nike Zoom Rivals s8 (sprinting spikes) and I was wondering whether I should use them for 400/800m races. If so, what length spikes i should wear for each race. (I also do the 100/200m occasionally.) 3 options: I have the 1/8 inch inch metal spikes, 3/16 plastic spikes and 1/4 inch plastic spikes. Thanks
