OS Runners are invited to participate in the annual Alumni Cross Country Race in London which returns this year, after a two-year hiatus, on Saturday 11th December 2021.

The long-standing race is hosted by Thames for old boys of schools with strong cross country running traditions and started in 1953 and continues to grow in popularity. The course of 5 miles on Wimbledon Common is a shortened version of the Blues Race course.

All ages are welcome – seventy year olds compete with eighteen year olds – the fastest time is usually close to 25 minutes and the back markers closer to 60 minutes.

Two years ago, the OS Running Team- featuring a record number of alumni and staff- achieved terrific results by winning the Ladies event and finishing second in the Men’s Open Race, beating out stiff competition from over 200 runners of 22 other schools.
