Sadly, the pro road racing season is over in Europe and North America for another year. If you want to get a fix of cycle racing in the Northern hemisphere between now and the Spring Classics you need look no further than 6 day racing.
It's a little known fact that 6 day racing first began, just round the corner from where in live, at the Agricultural Hall in Islington, London in 1878. A fellow by the name of David Stanton bet he could ride 1,000 miles in 6 days. Stanton started at 6am on 25 February and won the bet in 73 hours. Incidentally he made £100 from the bet.
As time passed 6 day racing grew and the format of the racing changed to allow teams, usually made up of 2 riders, 1 raced while the other rested. The 24 hour regime was relaxed and replaced with a more typical 6pm to 2am schedule on indoor tracks (velodromes). The overall winner of these events was the team to complete the most laps. If teams finished with the same number of laps the winner would be the team with the most points won in intermediate competitions.
Typically 6 day events usually consist of motorpaced, intermediate sprint and elimination races. The main event is the madison which derives it's name from Madison Square Gardens in New York where the 2 man chase format originally came from. Both riders will be on the track at the same time and take it in turns to race by hand slinging each other back into the action.
Pre World War II 6 day racing was extremely popular in the Untied States. However, there was a decline in popularity after the early 1900s in line with the rise of the automobile. By 1950 6 day racing had pretty much died out in the USA.
6 day racing is predominantly a European phenomenon these days, especially in Belgium and Germany in cities such as Ghent, Berlin, Bremen and Munich amongst others.

In addition to track racing, spectators may also be entertained by live music and have access to restaurants and bars. Nightclubs are also not uncommon and usually stay open until well after the racing has finished at 2am.
I have to admit I have never been to a 6 day event but will try my hardest to get to one in the early part of next year. I can think of nothing better than watching track racing whilst necking too many delicious Belgium or German brews, sounds like heaven!
