Fit & Fun |

Before kicking back to watch fireworks paint the sky during the annual Family 4th at Lake Union celebration, consider stretching your legs to soak up local history.

The Museum of History & Industry (MOHAI) and One Reel have organized the six-mile, 15-question Cheshiahud Challenge, a local-history trivia game for walkers and bicyclists.

Participants will loop the lake, visit parks along it and arrive at "trivia stops." Each participant will record answers on his or her game map to potentially win 3-Day Gold Passes to Bumbershoot.

Official game maps can be downloaded and printed in advance from family4th.org or seattlehistory.org. The maps also will be available between noon and 6 p.m. at MOHAI's booth in Lake Union Park, the Information Booth in Gas Works Park and in front of Starbucks stores at 1200 Westlake Ave; 2110 N. 45th St.; 3415 Fremont Ave.; and 2344 Eastlake Ave. E.

The challenge accompanies the 36th annual Lake Union Wooden Boat Festival, which runs from Saturday to Wednesday. A rundown of festival activities can be found at cwb.org/2012Festival.
