Read carefully, I did 3K TT
Current VDOT= approx 66-68...(based on LT pace, 5k pace and easy pace on treadmill)
Tell me your data:
3) Threshold heart rate range
4) 1h running pace at 70%HRmax-90%HRmax, but tell exact 1h avg pace/avg heart rate (of course don't tell me any yours PRs, don't include here half marathon running if it is withing 1 hour :-)) ).
I will tell you your marathon prediction and current VDOT, and you compare with real one, ok?
If you want more accurate forecast, give me 5-7 1h runs
