Capital BMX is a BMX racing club at Ian Galloway Park in Wilton, Wellington. It is a registered charity and incorporated society, run by a volunteer committee, and it looks after the park's BMX track. The track is open to the public for free when the club is not using it. The club is part of the Wellington Regional BMX Association with the Hutt Valley Thunderbolts and Kapiti BMX, and it is affiliated to BMX New Zealand.
Each Sunday morning, year-round and weather permitting, the club runs racing at the track. Three free "Have a Go" sessions run from 9.30am to 10.15am before racing starts. Bikes, helmets and gloves can be borrowed, and riders are asked to wear long sleeves, long trousers and closed shoes. Strider riders and parents riding with children are welcome. Members train on Thursdays from 4.45pm to 8pm during daylight saving months. Riders train in ability groups: Sprocket training covers basic skills, juniors and intermediates have skills and race training, and senior riders follow their own programmes. The club's juniors have recently raced at national and regional events, including the Wellington winter series.
