The Sidlaw Swoop organised by Tay member Gillian Tuddenham Saturday 14/12
This isn't a Tay event although several Tay members go to the Scottish mountain Bike Orienteering Events. They are under the SMBO/BMBO umbrella not BOF and you need to buy an annual BMBO membership which unfortunately runs out at the end of December, and pay your entry fee. An OS map is used not an O map and you can go as an individual or a pair. SI punching is used. There are lots of prizes and it's usually fun in an area with lovely scenery.
