Davidson was well prepared for the 22km Sport Ride category at Bannockburn alongside his daughter, Tyla, and said the heat of the day paled in comparison to the extremes of the 4500km Tour Divide race he did in 2014 and 2015.
"Conditions [in the Tour Divide] went from -10degC up to 40degC."
Davidson rode for up to 18 hours a day in the event, which starts in Banff, Canada, and finishes in Antelope Wells, at the New Mexico border. Only about 60% of entrants finish the race each year. In 2015, Davidson finished 11th out of 170 riders. He is planning on competing again next year.
More than 300 cyclists took part in the 22km Sport Ride, 35km Classic Ride and 10km Recreation Ride categories of the Bannockburn event, which is part of the Cromwell Summer Series.
Another 70 took part in a new category this year, the 56km Adventure Ride, which featured a challenging course that included steep climbs.
Event organiser Bill Godsall said the new Adventure Ride was added to "keep challenging" the more experienced riders who had previously done the Bannockburn event.
The category attracted various nationally known athletes, including mountain-biking brothers Craig and Ben Oliver, gold medallist rowers Nathan Cohen and Carl Meyer, mountain biker Josie Wilcox, multisport athletes Steve Gurney and Natalie Jacobs, Central Otago mountain-bikers James Williamson and Fletcher Sharman and Queenstown mountain-biker Erin Green.
The Cromwell Summer Series will conclude with the Lake Dunstan Triathlon/Duathlon on January 2, and the Lake Dunstan Cycle Challenge on January 8.
