TVSS on MapRun

New to MapRun? Read our user guide here.

The Summer 2021 Thames Valley Street Series (TVSS) is now open.

To find all events on the MapRun app, open the app, click on Select Event > UK > Thames Valley > TVSS. Note that this folder contains some older events from last year as well, but we have named things carefully and the event you are looking for should be easy to find. However, you may need to scroll down a bit.

Please note that these events involve road crossings and, as such, are not suitable for unaccompanied under-16s.

To access the pdf map and control descriptions, click on the event name (hotlink) below. Maps are 1:10,000 unless otherwise noted. White areas are OOB even if they appear to be crossable on the ground; yellow areas may be traversed.

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. There have been some exceptions to this.

To see the results, including tracks for all runners, click here and type TVOC TVSS into the box. Please do not look at the results of any given event, even just the scores, before you have run it – this gives a significant unfair advantage.

Event 4: Marlow, planned by Bob and Pattie Beresford, TVOC. Open until 22nd August. Full instructions on the back of the map.

Event 3: Sonning Common, planned by Mark Saunders, TVOC. Open until 22nd August. Full instructions here. Please note this event has an unusual format, being an odd-even score. Please read the instructions carefully to ensure you know the rules!

Event 2: Thame, planned by Ben Green, TVOC. Open until 4th July. Start/Finish in Victoria Mead, OX9 3HY; plenty of street parking available nearby.

Event 1: Beaconsfield, planned by Robin Bishop, TVOC. Open until 20th June. Full instructions and control descriptions here. (Note that this event is dated Jan21 in MapRun. It was indeed set back in January, but lockdown restrictions meant it could not be run until recently so it is being included as the first event of our summer series.)



These events from past leagues are all still available in MapRun but have now closed for league scoring purposes. If you wish to see results for the Oxford city events, type OSS instead of TVSS in the link above.

Botley (Jan 21), planned by Simon Ross, TVOC. Starts and finishes in Toynbee Close, Botley, OX2 9HW.  There is ample on-street parking with no restrictions in the area.  The map takes in streets and footpaths which at this time of year are very muddy so trail shoes are definitely recommended.  The A34 cuts across the map North to South and can only be crossed at three locations (all via underpasses) next to controls 10, 11 and 12.  Should you choose to cross at control 12 you will need to run on the wide pavement alongside the A34 – this footpath can be clearly seen on the map.  Please take care if using this route.  The majority of controls are lamp-posts but there are some variations so please refer to the separate description sheet. Sites should be obvious from the map anyway as long as you’re in the right place! 

Princes Risborough with Whiteleaf (Dec 2020), planned by Neville Baker, TVOC . Start and Finish are at the junction of New Rd and The Crescent, Princes Risborough – plentiful street parking is available nearby. Note that the map includes controls in the Brush Hill Reserve and Whiteleaf Hill. Expect severe climbs should you choose to try for these controls. It is forbidden to run on the middle portion of Peter’s Lane, which is steep, sunken and can have fast traffic. Care should be taken crossing any part of this lane. Finally note that this area has a few extraneous features on the map (such as the occasional wall) which should be ignored.
There is an impassable path on the map due to vegatation.
The long diagonal path NE-SW in the centre of the map just above the 35 control number is blocked with vegatation.
The path routes from 27 to 15 or 32 which extends the above path on the NE side of the road towards the NE are clear.

North Abingdon (Dec 2020), planned by John and Kathryn Turner, TVOC. The Start/Finish is at the Lamp post at the far end of Rutherford Close OX14 2AT. From the Oxford Road, Abingdon, turn into Appleford Drive at the traffic lights adjacent to the Boundary House Pub. Parking can easily be found in adjacent streets. Please do not park in Rutherford Close itself. Control numbers 11 and 14 are Footbridges. All the remaining controls are Lamp posts. 

Marlow North and Marlow Bottom (Nov 2020), planned by Bob and Pattie Beresford, TVOC. Another bespoke map from the Beresfords, and this should be a real treat. Full instructions on the back side of the map linked above.

Oxford East (Nov 2020), planned by Oliver Paulin, OUOC. Start is on the Cowley Marsh Recreation Ground. Parking ought to be possible on nearby streets if you choose your time carefully.
