The GD Champs is a bike race that commemorates George Dummer, a talented mountain biker and all round local legend from the Southern Highlands of NSW, who tragically passed away in 2020, aged 14. The inaugural event included Oxley College and Chevalier College. In 2022, 107 riders from many schools competed and the format changed to Enduro. In 2023 we opened the GD Champs to riders of all ages.

An Enduro Format, the GD Champs features 3 fast, fun, flowing (mostly downhill) trails of 1-2km at Welby mountain bike trails. Ride all 3 trails as many times as you like to record your best times.

Categories for all age groups (U9, U11, U13, U15, U17, U19, open, 50+) and E-bike.
