A Fat Tire Bike Race that takes you from downtown Seabrook onto the beach for laps before returning to downtown Seabrook. Bring your Fat Tire Bike (or mountain bike, FYI the course is 60% sand) and come pit your skills against other Fat Bikers! This race follows a similar formate to a cross-country mountain bike race. The start and finish are removed from the beach laps on the sand, with leaders determining the number of laps raced, restricted by the overall time limit. 

With FOUR categories to choose from, you will find one heck of a race to be enjoyed! The categories are as follows:

U13 (under 13 years old) - 1 Lap of course (1.5 miles)

Category 3 (beginners) - 30 minutes

Category 2 (Intermediate) - 45 minutes

Category 1 (expert) - 60 minutes

E-Fat (pedal assist electric fat tire bikes) - 35 minutes

The course starts and finishes on Market Street of Seabrook. You are sent out to the beach from the start where laps will be completed on a closed course before being sent back up to the finish with the goal finish time window kept in  mind. YOU ARE NOT GUARANTEED LAPS. If you are passed by the leader, you will be shorted laps. This is a race over a sandy surface and tire widths greater than 3" will see the most success. 


Don't have a fat tire bike? Buck's Bikes has a limited number of bikes available for your race as a $25 rental fee. Due to availability, it may be necessary to immediately pass off the bike at the conclusion of your race. Also be aware there could potentially be a rider who needs to finish their race before you get your bike. Don't worry! The race won't start without you! Buck's Bikes does NOT have E-Bikes to rent, if you are participating in the E-Bike category you must bring your own bike.

There will also be a complimentary bike wash station at Buck's Bikes, open all day long, fully stocked with water, brushes, cleaning solutions, and chain lube! Nobody likes a rusty bike....
