The first 20+ min of film is work over hurdles. We run about 30m into and out of the hurdles. Then the final 10+ min of film is work over the barriers, practicing stepping on the barrier and pushing off. This is only the second or third time that they have gone over the hurdles and barriers; we especially want to get comfortable stepping onto/off the barrier before we add the aspect of a giant pit of water to deal with as well.
