Graeme Obree

In March 2018, Obree tested another replica of Old Faithful in the Mercedes-Benz F1 team's wind tunnel to gauge the aerodynamic efficiency of his various riding positions on the bike, having never previously participated in wind-tunnel testing before. It was found that the CdA (drag coefficient) of Obree's initial "tuck" or "crouch" position was 0.17, compared to a conventional 1990s bike position of 0.20 and a modern conventional position of 0.188, leading to an estimated gain in speed of about 2-2.5 km/h over his rivals in the nineties and a gain of 1.5 km/h over contemporary track cyclists: meanwhile the "Superman" position was found only to be marginally more efficient than the 1990s conventional position, and less efficient than the modern conventional position. Obree however noted that the discomfort of the "crouch" position takes a lot of energy out of the rider through holding the hands and shoulders in place, whilst the "Superman" position was much more manageable.

Battle Mountain: Graeme Obree's Story, a documentary film about Obree's appearance at the 2013 World Human Powered Speed Championships in Battle Mountain, Nevada, premiered at the 2015 Edinburgh International Film Festival. The film, directed by David Street with music by Alun Woodward of Chemikal Underground, went on public release on 21 March 2016, with a tour of cinemas featuring a question-and-answer session with Obree following screenings. The film was crowdfunded through the Kickstarter website.

In January 2011, Obree disclosed in an interview with the Scottish Sun that he is gay and that his difficulty with coming to terms with his sexual orientation contributed to his earlier suicide attempts. "I was brought up by a war generation; they grew up when gay people were put in jail. Being homosexual was so unthinkable that you just wouldn't be gay. I'd no inkling about anything, I just closed down." He came out to his family in 2005.

In December 2011, Obree announced that he would make an attempt at the human-powered vehicle (HPV) land speed record, hoping to hit 100 mph. In May 2012, he revealed that the bike he is building for this attempt is a prone bike. The attempt was originally to take place in Britain, and the record speed was then 82.8 miles per hour (133.3 km/h). However, he competed in the 2013 World Human Powered Speed Championships in Battle Mountain, Nevada, where the record was also set. He achieved a speed of 56.62 miles per hour (91.12 km/h) on the morning of Friday, 13 September.

In March 2010 he was inducted into the Scottish Sports Hall of Fame.

In May 2009, Obree announced that he would make an attempt at the "Athlete's Hour" record on a bike he had built himself during 2009. Obree said in October 2009 that the attempt had been cancelled as the bike he'd built himself was not suitable for the conditions. He will not be attempting this again.

In December 2009, he was inducted into the British Cycling Hall of Fame while in March 2010, he was inducted into the Scottish Sports Hall of Fame.

His life and exploits have been dramatised in the 2006 film The Flying Scotsman and more recently in the documentary film Battle Mountain: Graeme Obree's Story, which follows his journey to Battle Mountain, Nevada to compete in the 2013 World Human Powered Speed Championships.

He published his autobiography in 2003 titled The Flying Scotsman. He said: "It started with the psychologist saying it would do me good and ended up as my life story." A film based on the book premiered at the Edinburgh International Film Festival in 2006, starring Jonny Lee Miller and Billy Boyd. In November 2006 Metro-Goldwyn Mayer bought world distribution rights and the film was released in the US on 29 December 2006; it was given a UK release on 29 June 2007. The DVD was released in the UK on 5 November 2007.

Obree is divorced from his wife, with whom he has two children. He continues to race occasionally in individual time trials for Ayrshire-based Fullarton Wheelers cycling club. In May 2005, he crashed in the rain in the national 10-mile time trial championship near Nantwich in Cheshire. He was a member of the winning three-man club squad that took the team title in the Scottish 10-mile championship in May 2006. In December 2006, he competed in the track event, Revolution 15, in a four kilometre pursuit challenge.

Obree developed another riding position, the "Superman" style, his arms fully extended in front, and he won the individual pursuit at the world championships with this and Old Faithful in 1995. That position was also banned. However, in May 2014 the UCI relented, acknowledging that fixing the kind of equipment to be used was hindering technical progress. It restored previous banned world records, from 2000, now to be described as "Best hour performance".

Francesco Moser, whose record Obree had beaten, adopted Obree's riding position—adding a chest pad—and established not an outright world record but a veterans' record of 51.84 kilometres. He did it on 15 January 1994, riding in the thin air of Mexico City as he had for his outright record, whereas Obree and Boardman had ridden at close to sea level.

Obree retook the record on 27 April 1994, using the track that Boardman had used at Bordeaux. He had bolted his shoes to his pedals, to avoid what had happened in the final of the national pursuit championship, when he pulled his foot off the pedal during his starting effort.

He rode 52.713 kilometres, a distance beaten on 2 September 1994 by the Spanish Tour de France winner, Miguel Induráin.

Obree's brother, Gordon, died in a car crash in October 1994, and Graeme Obree again slid in and out of depression. In 2001 he was found unconscious at Bellsland Farm in Kilmaurs, 12 km from his Ayrshire home. The Obree family horse was stabled there, and he was discovered by a woman checking a barn. He had tried to hang himself. His wife, Anne, said he had been diagnosed as having severe bipolar disorder three years earlier.

Obree attacked Moser's record, on 16 July 1993, at the Vikingskipet velodrome in Norway. He failed by nearly a kilometre. He had booked the track for 24 hours and decided to come back the next day. The writer Nicholas Roe said:

On 17 July 1993, Obree set a new record of 51.596 kilometres, beating Moser's record of 51.151 kilometres by 445 metres.

Obree's triumph lasted less than a week. On 23 July 1993, the British Olympic champion, Chris Boardman broke Obree's record by 674 metres, riding 52.270 km at Bordeaux during the rest day of the Tour de France. His bike had a carbon monocoque frame, carbon wheels, and a triathlon handlebar. Their rivalry grew: a few months later Obree knocked Boardman out of the world championship pursuit to take the title himself.

Obree was individual pursuit world champion in 1993 and 1995. He broke the British 10-mile individual time trial record in 1993, won the RTTC 50-mile championship the same year (a record 1h 39m 1s), and won the 25-mile championship in 1996. In 1997 he joined forces with coach Joe Beer and clocked 18m 36s in a 10-mile time trial (V718 Hull) and next day won the British Cycling Federation 25-mile championship - this was part of building towards an hour record attempt that was to be eventually shelved.

Obree suffers from bipolar disorder. He attempted suicide in his teens by gassing himself. He was saved by his father, who had returned early from work. In the 1990s he took an overdose of aspirin washed down by water from a puddle. He had personality problems, sniffed the gas he used to weld bicycles, and was being chased for £492 owed in college fees.

Graeme Obree (born 11 September 1965), nicknamed The Flying Scotsman, is a Scottish racing cyclist who twice broke the world hour record, in July 1993 and April 1994, and was the individual pursuit world champion in 1993 and 1995. He was known for his unusual riding positions and for the Old Faithful bicycle he built which included parts from a washing machine. He joined a professional team in France but was fired before his first race. He also competed in the men's individual pursuit at the 1996 Summer Olympics.
