Sam Whittingham pedals streamlined bicycle, the Varna Diablo III at 53.918 mph (86.711 kph) average speed for one hour (60 minutes) at the Nissan Technical Center Test Track near Casa Grande, Arizona April 8, 2007. This is a new World Record. Video from officials in chase car during last 1min 30sec of his run. To the best of my knowledge, this is the only video that exists of his run. About 100 people were at the track that day, many of them preparing their vehicles for their own attempts on the record.
Sam doesn't come into view until about 1 minute into this video. Though if you look hard around the turn you can see his white bicycle on the track. The chase cars were supposed to stay back for the riders safety. In the last 30 seconds or so, we pull along side Sam to throw the chalk bag to mark the spot where he finishes. Officials at the timing station called out the final seconds 10, 9, 8, 3, 2, 1...

The Hour Record which is simply how far a cyclist can go in one hour from a standing start is one of the most famous records in cycling. Whoever holds it becomes internationally known within the sport of cycling. In recent years, this record has been held by the likes of Graeme Obree, "The Flying Scotsman", Miguel Indurain, Tony Rominger, Ondřej Sosenka and Chris Boardman. Sam's record belongs in a "human-powered vehicle" category where aerodynamic fairings around the vehicle and rider are allowed. It is currently the farthest any human has ever gone under their own power in one hour. Chris Boardman, a professional cyclist, holds the current record for pedaling a bicycle without any aerodynamic fairings of 35.03 miles, (56.38 kilometers) in one hour set in 1996. Sam's record of nearly 54 mph is significantly faster for one hour, than the fastest (about 45 mph) that cyclists in the Olympics or Tour de France can reach for only ten seconds or less.

The Varna is a streamlined recumbent bicycle. There is no motor inside. Sam was 35 years old when he set this record and a former member of the Canadian national cycling team. In a very similiar vehicle, named the Varna Diablo II, Sam went 81.000 mph (130.36 kph) through a 200 meter timing trap on a course near Battle Mountain, Nevada. This is currently the fastest a human has pedalled a bicycle under their own power, on flat ground with no drafting of a vehicle. See YouTube video "Worlds Fastest Bicyclists", shot by the Discovery Channel. It should be an eight-minute clip.
