On your mark, set, register.
Registration for next spring's Boston Marathon opens Monday, and with demand high, the Boston Athletic Association is urging qualified runners to do something that should come naturally: Move quickly.
As in recent years, the BAA will use a rolling registration, with the fastest qualifiers in their gender and age groups getting the first crack at a coveted bib. Sign ups begin at 10 a.m. at baa.org for runners who qualified with a time 20 or more minutes quicker than they needed.
Athletes must meet strict time standards for a shot at a place in the field of 30,000.
The 122nd running of the 26.2-mile race will be held on Monday, April 16 - the Patriots Day holiday in Massachusetts.
