He is a multiple national record holder with best marks including: 1500 metres, 3000 m steeplechase, 5000 metres, 10,000 m on the track, and 10 km, 15 km, half marathon and marathon in road events.[1] He won his fiftieth national title over all distances and surfaces in March 2011, claiming the Austrian half marathon title.[2]
He began to run over longer distances from 2007 onwards, moving away from being a steeplechase specialist. He started the year at the 2007 European Athletics Indoor Championships, in which he competed in 3000 metres and finished seventh. He came second at the 2007 European Cup 10000m behind André Pollmächer in his first appearance at the competition.[6] At the 2007 Osaka World Championships he suffered an injury after a collision with one of the barriers. He was subsequently rushed to hospital to treat facial injuries received in the fall which included a split lip, and a cut jaw. His was the most serious incident in a series of accidents in the long-distance events at the championships. Weidlinger was considered a certain qualifier and an outside medal chance. He returned to competition soon afterwards, taking tenth place in the 2007 IAAF World Athletics Final the following month and competing at his first IAAF World Road Running Championships at which he finished in 23rd place but set a national record of 1:01:42.[7]
Weidlinger competed at the Cinque Mulini cross country race in early 2008 and managed to finish in sixth place.[8] He set two new national records in May that year: first, he ran 27:36.46 in the 10,000 m at the Payton Jordan Cardinal Invitational in Palo Alto, California, taking second behind Craig Mottram.[9] He then set a 10 km Austrian record at the Great Manchester Run: his winning time of 28:10 was just enough to hold off Serhiy Lebid and Mustafa Mohamed at the finish line.[10] Weidlinger won the Group A 5000 m for a second time at the 2008 European Cup. He competed in the 10,000 m at the 2008 Summer Olympics in Beijing and finished 27th in a time of 28:14.38. This made him the fifth best performing European in the event. On September 1, 2008 he won the Nike Human Race 10K race with a time of 29:25 while running in Munich, Germany.
Marathon debut
His first major event of 2009 was the Vienna City Marathon, in which he finished in ninth place with a time of 2:12:39 for his debut over the distance.[11] In his second marathon outing, Weidlinger improved the Austrian record by over one and a half minutes at the Frankfurt Marathon on 25 October 2009, setting a new mark of 2:10:47 to finish in tenth place. The record was previously held by Gerhard Hartmann and had gone unbroken for over 23 years.[12] In November, he won the Great Australian Run in a personal best and national record time of 43:01 for the 15 km race, defeating 2008 Olympic champion Samuel Wanjiru among others.[13]
He returned to the Vienna City Marathon in 2010 and was Austria's best prospect for the podium. However, he finished in 12th place in 2:14:05 after suffering from a calf problem.[14] His next major appearance came at the Great South Run in October and he ended the race in sixth position.[15]
