Women's teams have overcome appalling weather conditions to dominate the 2015 WildEndurance event winning both the 50km and 100km teams event in the Blue Mountains at the weekend.
The Glenbrookers team of Sarah Highfield, Fiona Bedford and Simone Hayes from the Sutherland Shire completed the 100km course in 18 hours 42 minutes, while The Fostest team, comprising the inner Sydney trio of Froeydis Hegnar, Skye Blackwood and Olga Rosbourg, won the 50km event in 7 hours 34 minutes.
Only nine teams managed to complete the 100km event after the torrential rain made crossing Bedford Creek too dangerous.
"We had safety crews on site at the creek crossings, and when teams reported that the creek was beginning to flow soon after 5am on Sunday, we made a decision to stop the event for teams behind at this point to ensure the safety of competitors," said event manager, Sarah Williams, who established the event eight years ago.
"It was easily the worse conditions we've ever faced and it was a massive effort for the teams to complete the 50km event, let alone the 100km distance.
"Local runners, who are experienced with the event route, said they had never seen conditions this bad. It was like a swamp in several areas while the competitors were in waist deep water at Bedford Creek before we called off the event."
Competitors left Dunphys Creek in Megalong Valley on Saturday morning under threatening skies, and it wasn' t too long before the heavy rain fell.
The Glenbrookers were also the first team to reach the 50km mark and they finished the 100km distance three hours ahead of second placegetter, Crossfit Maitland, who took the 100km mixed team honours.
No all-male team reached the 100km finish mark inside the 30-hours time cut off point.
The Fostest won the 50km event by six minutes ahead of the all-male iRun team from Sydney's north shore, while Illawarra's Never Again men's duo was third.
The 50km mixed team event was won by Northern Beaches pair Guy and Simone Massey.
Conducted by The Wilderness Society, the event attracted more than 340 competitors and raised almost $150,000.
A portion of the monies raised will go to Science for Wildlife to track and save koalas in the Blue Mountains. The money will assist with the purchase of GPS tracking equipment and collars plus the training of koala detection dogs.
