Sir Bradley Wiggins is ready to embrace a challenge described by five-time Tour de France winner Eddy Merckx as his toughest on the bike.
Tomorrow, the 35-year-old Briton will attempt to break the UCI Hour Record at the Lee Valley VeloPark - formerly known as the Olympic Velodrome.
The current best mark for the furthest distance cycled in 60 minutes is held by Alex Dowsett, another Briton, who recorded 52.937 kilometres in Manchester in May.
The target Wiggins - the 2012 Tour de France winner, a four-time Olympic champion and the reigning world time-trial champion on the road - has set himself is 55.250km, or 221 laps.
Wiggins wishes to set a standard for his generation at his only attempt at the historic Hour, an event which in 1973 left Merckx exhausted and in awe of his own record-breaking feat.
"I'm confident," Wiggins said. "I try not to sound too arrogant because I have done my homework with it and I know what I'm capable of.
"I have also been on the track a lot and know exactly what I can sustain now for one hour."
