The Boston Athletic Association said on Tuesday approximately 2,181 runners sought medical treatment in one of seven medical tents set up along the course or at the finish area of Monday’s Boston Marathon

As of early this afternoon, nine runners remained hospitalized in critical but not life threatening condition, according to a BAA spokesman.

About 500 more runners visited Red Cross aid tents, the BAA said. High temperatures were present throughout Monday’s race.

Estimates about the race were shared with the media at a post-race press conference Tuesday. Officials also said an estimated 215 runners were either taken to a hospital or visited one on their own, and between 15 and 20 were still receiving treatment at a hospital as of Tuesday morning.

Here’s a look at the other stats provided by the BAA:

26,716 entered the 116th Boston Marathon

22,863 picked up race numbers

22,535 started the marathon

21,603 finished the marathon

3,853 did not pick up race numbers

328 are eligible to defer their entry to next year. The BAA did say the number could increase because it is still sorting through additional requests for deferment based on entrants who chose not to travel and communicated their intentions after the deferral option was introduced on Saturday.

932 dropped out

The BAA also said no adjustments would be made to qualifying standards for 2013 based on the heat.
