Houstonians from around the city are invited to join Heights residents for a two-day bicycle rally and scavenger taking place over the June 10-11 weekend.

Hosted by the Houston Heights Association, the Heights Bicycle Rally & Scavenger Hunt has been taking place in the Heights for 18 years as a way to celebrate the neighborhood and promote community engagement, said Emmanuel Núñez, who chairs the event for the association.

Participants can choose either a 15-mile ride or a 5-mile ride designed for families with children, both of which also feature a scavenger hunt in the community. Entrants will be emailed a rally map and scavenger hunt clue list the day before the event begins, according to the event website. Clues describe sights or objects that can be seen along the rally course.

The rally will begin at 8 a.m. June 10, and clues must be turned in to at the Heights Fire Station—107 W. 12th St., Houston—by 3 p.m. June 11. Clues can also be turned in at an afterparty slated to take place from 3-5:30 p.m. June 11 at Marmion Park, 1800 Heights Blvd., Houston. The event is not considered a race, and participants are encouraged to work through the course at their own pace.

The afterparty will feature door prizes, live music and vendor booths showcasing local businesses. Eureka Heights will be on hand providing refreshments. Winners—determined based on which entrants find the most mystery objects based on clues—will be announced at 5 p.m. June 11.

Proceeds from the event support the nonprofit Houston Heights Association, which is dedicated to preserving the character of and enhancing the Heights community through maintenance, restoration and beautification projects, according to its website.

The event is open to all ages. Those interested in participating can sign up online. Participation costs $25 for the 15-mile ride and $15 for the 5-mile ride.
