Qualified for Boston with a low 2:47. Aiming to run significantly faster. Concerned about corral placement. Last year's popularity skewed the first corral faster. Assuming it returns to historical average, I think my time should be fast enough to get in that corral.
My question is--if I'm not in the first corral, how will that affect my goal of running under 2:35? Does corral placement matter that much? This will be my first time running Boston.
