these short races can get ya. ie: I planned to run 8 flats at that 4 miler trail race. I was also planning to take off cold. BUT, I was soo antsy and the race was short enough, and BOTH you and I are in good enough shape we have endurance to burn. I did a warm up run,, about 20 minutes- 2 miles... then I stretched, and then raced. ended up with 7:33's I WAS SHOCKED!!!! 27 seconds per mile is HUGE!
I came out of the start very strong, and then realized my legs had no warm up to make, they were ready to rock and roll.
Race dynamics are such that you will get comfortable and take off, and hammer those legs,,, it's fine for a mile or two, but going into mile 3 you may experience a lil hammy trouble.
IN YOUR case, and MINE, screw everybody else... As long as you are doing these short races, a warm up run, and little bit pof stretching my be a good idea.
Be careful of dynamic stretching on a race day. You will have added nervouis adrenaline and tension on race mornings. SO, a 11-12 munte mile or two, and then a nice slow static stretch for your parts.
you made it thru the curve man!!
