Two teams of charity cyclists arrive in London today having ridden all the way from Europe to celebrate the Olympic and Paralympic Games.

A group of 150 orange-clad Dutch cyclists will pitch up at the Oranjecamping site in Walthamstow at 3pm this afternoon. They’re sportive cyclists on a tour organised by The Royal Dutch Cycling Federation (KNWU) that saw them ride from Utrecht, via Hoek of Holland and Harwich to London. Their arrival heralds a week of Olympic celebrations at Heineken House in Alexandra Palace. The cycling team is led by Olympic snowboarding champion Nicolien Sauerbreij and accompanied by the illustrious Dutch umpa band Kleintje Pils.

Another group of 20 cyclists from the Austrian Tirol will reach London Bridge today after their eight-day, 1,300km charity ride from Innsbruck. The ride was in aid of British charity Disability Snowsport UK (DSUK).

Supporting the Tirol cycle team at the start was the UK’s Heather Mills, hopeful for the Paralympic Games in Sochi 2014 for the British Disabled Ski Team, who joined them as they set off from the Bergisel stadium. During the ride’s final stage from Ramsgate to Tower Bridge, British sport personalities will join including BBC Ski Sunday presenter Graham Bell and ex GB ski racer Konrad Bartelski.

The Tirol team’s arrival coincides in with the official opening of the Olympic hospitality house, Austria House Tirol, at Trinity House.
