Stealing Flagpole's thunder, but actually have a question. Three weeks and 2 days til Boston. I had planned on my last 20 (21 actually) miler being last Sat. (4 weeks out). I think I will do a 20 closing hard the last 4 tomorrow. I remember last marathon doing last 20 4 weeks out and by the time marathon day came, it felt like it had been too long (may have just been mental).
What's your take on last 20 miler , 3 or 4 weeks out?
