Filled in for Sonia who had to drop out due to knee injury. Brilliant sunrise on drive over but foggy for first 20km or so - water dripping off helmet and had to take glasses off. Sun at first feed stop. A couple of tough hills early on passed a few riders but on the flat I soon dropped back. Food stops in odd places for me - passed a few riders on the first long hill and arrived at feed station to see fast finishers heading back already having done the end loop. Busy down into Noojee but excellent and steady road back up - best bit of the day - rolling hills but "all downhill" back to finish. 9 cars left in carpark - rolled in as Hells 500(?) appeared shepherding their recruits so considering I was solo that cheered me up, most of the Hells 500 riders passed me at speed on the last loop and pretty sure some of their slower riders and a few others I'd passed turned back at the final feed station.
Polar gives average speed 20.6km/h with an excellent max of 61.7
results sheet gave all inclusive time of 7hr 10min
Av cadence okish at 77 Polar says 1680m ascent so 99% a Mont Ventoux day ridewithgps makes it a bit more i think
