If you're looking to participate in the 35th annual Boilermaker, you better sign up quick. WIBX is reporting that the remaining spots are quickly running out.

Race Director Jim Stasaitis told WIBX that at this pace, the Boilermaker will “sell out” by the end of the month.

According to officials, 2012′s registration numbers are more than double the amount at this time for last year’s Boilermaker, when only 4,266 people had registered for the main event and 425 had signed up for the 5k.

In addition, so far more women have registered to participate than men, filling up 51 percent of the field. If these numbers hold, this would be the first year where women make up the majority of runners.

The race is scheduled for Sunday, July 8th.”

So far a total of 10,657 people have signed up to run the 15k, and 1,027 people have registered to run the 5k. Remember that this year the caps were raised to 14,000 runners for the Boilermaker and 4,000 for the 5k event.

If you haven't signed up yet you can do so here.
