Hi I wonder if anyone can help? We have a running club in South Manchester (as yet unaffiliated but this is around the corner) We regularly have 20-30 people turn up to our weekly runs. We do not charge anything. I know public liability is not a legal requirement. Since we do not charge would it be possible for anyone to ever sue us if they had an accident whilst running with us. it is difficult to determine when we become an 'organised group' as opposed to a bunch of friends out running.
