According to Sky Sports, Bradley Wiggins shows that he stays confident to to break fellow countryman Alex Dowsett's record of 52.937km in London's Olympic velodrome at the end of the week. The former Tour de France winner will aim to push himself towards 55,520 kilometers. But he knows that there are a lot of parameters to take into consideration.

"If the conditions are right on the day. They would have to be really right. A lot of the hour record is dictated by temperature and air pressure. Air pressure is everything. The weather forecast for the first week in June is abnormally low pressure for London for that time of year, which is fantastic. That has dictated everything. You could go a kilometre either way depending on air pressure."

One of the most important thing is the pace judgement. "It is everything in the hour record," he told them. "If you can ride 16.1 or 16.2-second laps constantly for 221 laps, and not go 15.9s or 16.4s, it's keeping it on the line every lap, lap after lap. The most efficient way is to keep the power [constant], and that in itself is a skill. If you look at Alex Dowsett's [graph], he went like that [upward line] because he went faster, but people like Thomas Dekker [who failed in an attempt in February 2015] were all over the shop."

"It's like sitting on the motorway in the fast lane revving it in third gear, braking really hard, revving it. It's just a case of putting it in cruise control at 70mph and sitting. It's the most efficient way for a record like this."
