Battersea Street-O Results

Thank you all for coming to last night’s street-o in Battersea and to Ed for organising! Here are the race results and Series Results have now also been added.

Ed says: “First, a big thank you to everyone who stepped up to help out on the night – setting up, marking answer sheets but most of all helping run the start and finish – it couldn’t have happened without you! Apologies to everyone who was confused by the missing elliptical running machines at control 29 on Clapham Common – they were there when I set the course! The correct answer is of course “zero” but everyone who put some answer down has been credited. No apologies to those who were tricked into trying to run across Battersea Railway Bridge or through the Morgan’s Walk estate by Battersea Bridge – the map is fairly clear. Hope everyone had as much fun running as I did setting the course. “

Ed’s also got some lost property including a headtorch, a hand torch and phone! Please get in touch on to claim.

The next race is in Ealing / Brentford on Tuesday 10 December with details to follow shortly. Hope many of you can join us then!

Battersea Street-O, Tuesday 12 November

Welcome one and all to our third Street Orienteering Race! After two slightly-further-out races we return to central London, and more precisely lovely Battersea! Do join us for an evening’s racing & chat. Our meeting point this time is the Duke of Cambridge pub at 228 Battersea Bridge Road, SW11 3AA.  It’s not too far from Clapham Junction and a number of bus routes stop very close by. There’s also a Santander Cycle rack a couple of minutes’ walk away. We have a nice private area in the pub so do stay for a post-race chat & some food and drink afterwards!

Wimbledon Street-O and Overall Results

Last night saw the final street orienteering race of the 2018-19, on a wonderful sunny evening in Wimbledon. Thank you to Bob and Bex for (once again) organising a great event and to around 100 of you for taking part! You can now find the Day Results with Simon Wright and Ed Catmur on an exactly equal 674 points to take the win, and Vinh Hoang once again taking the women’s crown.

You can also find the Final Series Results for the 2018-19 season, with street-o stalwart Ed Catmur taking his 7th series win, followed by James Fraser and Steve Clelland. In the women’s category, Vinh Hoang was the runaway winner (taking 12th place in the overall rankings) followed by Camilla Brueton and Elaine Battson. A special call-out also goes to Ed Forman and Roderick Hoffman who attended all 9 races of the season.

Thank you to all the organisers who made the series possible, and I look forward to seeing you all again in September for the next season.

Matthias Mahr, street-o coordinator
