The Houston Heights Association has moved up its fall biking event to take place during Memorial Day weekend, May 23-25.

The 15th Annual Houston Heights Bicycle Rally & Scavenger Hunt is a three-day, 15-mile event for riders of all ages at any pace. A 5-mile route is also available for children and parents.

The event is not a race but rather a scavenger hunt in which riders will have to solve clues to progress through the route.

Early registration is open through May 21. Tickets are $20 for the 15-mile route and $10 for the 5-mile route, increasing to $25 and $15 on May 22. Registration closes May 25 at noon.
