I've decided that club C25K needs a secret wave (see today's earlier post). It needs to be known to only C25Kers but instantly recognisable. It needs to look just like a normal jaunty wave ( normal as in not making us look any crazier than we already are) and not get us arrested. We could then bowl along waving to all other runners but instantly identifying any of our C25K buddies.
Any ideas?
