Boston Marathon tomorrow

We made it safely into Boston yesterday and I'm just relaxing and waiting for the race to get here tomorrow. The weather has been cold and raining off and on but the weather forecast is looking pretty good for the marathon tomorrow. It's supposed to get down to the low 40's tonight so I'm expecting it do be in the mid 40's at racetime. I feel pretty relaxed because I don't really have high expectations of a specific time I think I should be able to run. My hamstring still isn't 100% but it's much better than it was before Houston. I think I've lost a little of my speed from the fall but my endurance is better. I will be reasonably happy with anything under 2:50. I'm planning on trying to run 6:25 pace the first 4 miles to take it easy and then stay in the 6:20-6:25 range for the first half of the race. I really want to try to negative split the race and if it's cool enough then I may wear my Kenyan Way negative split shirt during the race. I didn't realize it beforehand but it seems like half the Kenyan Way group is staying at the same hotel as I am. I've run into 4 or 5 of them in the lobby. It should be a good day for running tomorrow.
