It's not too late to sign up for the Boilermaker Road Race. With only 46 days until race day, there's still 600 15K bibs left up for grabs. 

A few years ago, the race sold out in a little more than two hours. But since then, organizers changed the race's registration format, and it's taken longer to fill up. 

The 15K race is capped at 14,500 runners. The last day to register is June 15th. 

"There's plenty of time, but don't sit back and wait because you're probably not going to be able to get anything the day before the race, so if you're planning on running the 15K, boom, get in there, get registered and get it done," said race director Jim Stasaitis.

The 5K sold out last week. Race day is July 9th.
