About 4 Fore 30 Infinity

We're back for the 8th year and it's going to be bigger and better than ever!

4 Fore 30 will follow all the rules of Big's Backyard Ultra.

At 7:00am on Saturday, November 15, 2025 everyone will line up at the start and have 1 hour to complete the 4.1667 mile course. Go as fast or as slow as you want, just be done in an hour, because... at 8:00am everyone lines up to do the next loop. At the top of each hour, the process repeats until there is only one person remaining.

All runners will receive race swag and something fun.

100% of profits go to the Kids' Harbor Child Advocacy Center.
