The to-be-built indoor cycling velodrome at Detroit's Tolan Playfield will host USA Cycling men's and women's U.S. National Track Championships in 2017 and 2018.

The three days of cycling are scheduled for Oct. 19-21. Next year's dates have not yet been set, said Dale Hughes, the velodrome's developer and organizer of the nonprofit Detroit Fitness Foundation that's working in collaboration with the city to create the privately-funded $4 million multisport building.

Ticket prices for the championships have not yet been set. The facility will have just under 1,000 seats, and Hughes said most of the audience will come from livestreaming.

The races are what is known as a madison tournament, which is two-rider relay team in a field of 20 to 30 teams.

The construction permit to build the 64,000-square-foot facility, which will include the cycling track and separate recreation fields inside an air dome, was granted Thursday, Hughes said. Work will begin this week, and the opening is scheduled for September. The general contractor is Wixom-based Quadrants Development LLC and Guelph, Ontario-based Farley Group is the air dome provider.

Hughes said he's seeking an international company to buy the naming rights for the facility.

The city announced the velodrome project in January as part of its planned improvements to Tolan Playfield at I-75 and Mack Avenue. The dome also will have indoor lanes for running, walking and skating, and a multipurpose infield. The park will get a playground, picnic space, a skateboard ramp and horseshoe pits.
