Have you tried XCO racing? Big Hill Events is hosting 2 rounds at Mount Avoca Winery, just 2hrs from Melbourne this weekend. Its a special venue to Rohin having grown up in Avoca and kept these trails alive for many years now to allow racing such as this.
There are no Day Licenses needed this weekend so very affordable race entry. Lets not forget that the 100% Organic wine at Mount Avoca Winery is amazing so great chance to have way more than a bike weekend.
