My goal is to break the school record for the 3200 which is 10:03 .my pr 11:20 at altitude off of 30mpw. This year in xc I ran 17:51 (previous pr 18:40) at altitude with a 11:30 2 mile split off 40 mpw. Is it possible to get close to 10:00 if I go up to 50-60 mpw and run at low altitude? FYI I live at 7000ft and both prs were set at 6500 ft.
