Between February and October, there are five Grand Slam Challenge rides throughout the Adelaide Hills, Barossa Valley, and Fleurieu Peninsula as part of the Grand Slam Challenge Series. Participants can ride in one, two, three, four or all five of the rides. Each ride combines two different loops of between 40km and 80km, all starting and finishing in the one location. There is also a Mini Slam for those looking for something a little less challenging, in which participants complete only one of the two loops.
Build up your fitness and increase your endurance throughout the year to complete the ultimate Grand Slam Challenge in October, or join us for one or two rides of the year. Meet new people, or meet up with old buddies, the Grand Slam Challenge rides are as much about the challenge as they are about the people you meet.
