I have been thinking of a strategy of doing my sub 1:40 and I have two strategies: run an even race or do a negative split. I can account for the first 5K and should be able to take care of the first 10 or 11k in the next 14 days. I have decided to be ambitious and see if I can meet my quest this year instead of the next year. If I fail this year, I will make next year's goal to be 1:30.
This is a draft. Strategy sessions continue.
