I understand that the strength endurance work on all these programs is running A’s but can you seriously tell me you have tried to doing these for 150m?? I mean that would take minutes and be extremely difficult even for the most well conditioned athlete…and if there are 2x150m in one session, are we just talking running high knees or are we talking the running A drill?? (one leg being lifted whilst the other stays straight, so we need to do one each leg to keep it balanced), so if we are doing 2x150m of running A’s in the session we are actually doing 4 reps over 150m…!!!
