The Sydney Summer Series Blue Gum event in Chatswood on Wednesday, 25 October 2017 is one of a series of running events timed over 45 minutes that involve visiting a variety of local features, or checkpoints.
These checkpoints are marked on orienteering maps that are used to help navigate your way around the local parks, streets and bush tracks where the events are held.
The checkpoints have different score values and the runners with the highest scores at the end of 45 minutes (in their age classes) are the winners. The Summer Series events are for everyone, attracting walkers and joggers through to champion runners. If you like running or walking with a navigational challenge, you will love the Summer Series.
