Acc Dev in GPP

my reasoning for the long run is both recovery and helping to prepare for cross-country (which is mandatory). After the Int. Temp day on friday the legs would be dead and a passive+active recovery day seemed like a good combination. Also the cross country meets will be on sundays so the setup somewhat mimics the college schedule so that the transition would be a bit easier. The 200 repeats are suppose to develop into kit-kats 5x200m to help with pacing and endurance i only foresee getting down to around 25.0 before the college training begins.He plans to do 500-800m and 60m indoors.

His school goes long-short in their training (all though they dont at all address speed work) so do you think that going short to long in GPP for 6weeks and then switching to the college program will have a bad effect?
