Prior to 2009, a 10K race had taken place at Roker along the coastline of Sunderland but the event was only open to female competitors; when it changed to permit male participants, it was re-styled as the Great North 10K.

The Winston Western 500 was an annual NASCAR Winston Cup race held at Riverside International Raceway in Riverside, California, United States, in January, and then in later years, November.  From 1963 to 1981, the race was held in January and was the season opening race.  NASCAR elected to start its season with the Daytona 500 beginning in 1982, so a second Winston Western 500 was run in November to accommodate the change; the change resulted in Riverside hosting three Winston Cup races in 1981.  The race ran in November from 1981 to 1987, serving as the Winston Cup Series' final race of the year from 1981 to 1986.  The race distance was 500 miles until 1977 when it was shortened to 311 miles (500 kilometers).  The other race held at Riverside, the Budweiser 400, was held in June. The 34th Great North Run took place on 7 September 2014 in Newcastle-upon-Tyne, England, United Kingdom with the men's and women's elite races and wheelchair races.  After having been narrowly beaten by Kenenisa Bekele in 2013, Mo Farah was rooted to become the first Briton since Steve Kenyon in 1985 to win the men's race and the first in any elite race since Paula Radcliffe won the 2003 women's race.  He broke the 29-year duck, helped by the absence of 2013 champion Bekele, and was only the third Briton to win the Men's Elite race.
