The Dams Challenge is NOT a race however we do time each rider.  The purpose for timing is to enable us to monitor your progress, locate you on the course and for your information.

Family and friends will be able to monitor your progress throughout the day with live-to-web streaming from check-points.

Due to the lack of communications in some areas not every check point will provide live results.  The final location of the timing stations will be announced in the rider packs.

The event had its genesis in 1998 and was first officially staged in 2010. It has quickly grown from little over 350 local riders to more than 2,000 participants from all over Australia and overseas.

The 5 Dams Challenge, that fabled endurance test for ageing cyclists, was conceived in a café on the terrace in Fremantle one Saturday morning in 1998. Was it possible to incorporate the five metropolitan dams into a single day’s ride? Intrepid rider Lindsay O’Brien thought so.

The following Tuesday he set out from Claremont, up the scarp at Lesmurdie and on to Mundaring. Then proceeding south to Serpentine, past the dam to the South West Highway and back to Claremont – 280km in just under ten hours.

Many different routes have since been used but all using the basic 5 Dams Challenge framework.

Solitude is the devil’s playground, so the ride is more enjoyable in a group. Many teams of riders have completed the ride, mainly motivated by Ian Pauley who initiated the Summer/Winter Solstice rides and has probably completed the ride more times than any other along with Graham Forward, Peter Gunzberg and Brian “Capo” Roberts.

The ride itself produces its own drama. The fatigue of ill-prepared riders brings out the best and the worst in them. The camaraderie such a ride invokes makes it a memorable experience.

An event like the Dams Challenge requires a small army of volunteers. There is no better way to get close to the action, gain experience for university or TAFE or just give back to the WA cycling community by volunteering your time and being part of a world class event.
