Had an injury over track season last year and was out and had a less than ideal cross country season, running 17:30 for my PR on a pretty hilly course.
Workouts I have done (all in January except for the first one):
5 miles 6:04 pace for a thanksgiving race- pushing but not crazy, just for fun.
Long run of 11 miles at 8 min pace (500 ft of uphill, 500 of downhill)
Quick 8 miles at 6:55 pace, a few hills, felt pretty comfortable, not pushing
10 miles @ 7:45 pace (like 500 ft of incline and 500 decline, so decently hilly)
20 min tempo run at 6:06 pace (felt really good, not pushing hard)
2.5 mile tempo run in 14:45 (5:54 pace) (felt really good, pushing a little)
I have my first indoor meet tomorrow, thanks.
If you had at least one day of specific track speed work, then I would say you have a chance.
Depends also on how you feel on race day. Bekele felt pretty good the other day, until the gun went off and he got trampled by amature runners.
A 10x200 @ 37 (race pace) w/ 100m jog recovery would be a start.
Have the last 200 be full out.
Let us know how the 1,600 goes.
