Thames Valley Street Series (TVSS)

The club is running a summer series of MapRun-enabled Street-O events during the summer of 2026, usually on a Tuesday evening. Details of specific events may be found on our main events page. MapRun is a free app which is fairly simple and intuitive to use.

In conjunction with the series there is an informal league. Results may be found here.

Your visits to control points will be registered using the app and GPS tracking. For the event you can either carry your phone or use a suitable Garmin watch on which MapRun has been setup.

Almost all of our events use the “Waikato Score” system: visit as many controls as you can in 60 minutes. 10 points for each control numbered 10-19, 20 points for each control numbered 20-29, and 30 points for the controls numbered 30-39. There is a penalty of 20 points for each minute (or part thereof) you are late back.

Inside the MapRun app, to find the our events go to UK > Thames Valley > TVSS > Summer26.

Events will be based at a pub and the printed map will be available there. You need to enter in advance from the event page (entry fee 3 pounds). These events password-protected – you will not get the password until you are ready for your run!

A Guide for planners is available.
