Helping out our local award winning race, the Ealing Half Marathon, has become one of our annual group sessions. The race is incredibly well organised and planned - we provide willing hands to put up advance warning signs on the route. There was some debate as to how far '200 metres apart' actually was - the next lamp post? The one after that? All very high tech.

We split into two teams, taking a side of the road each. There began a quiet sense of competition as we faced each other on opposite sides of the traffic. This was left unsaid, of course - it's better that way. An eyebrow movement can convey all it needs to, even through a couple of lanes of traffic bustle.

There's a fantastic atmosphere on race day at the Ealing half and we got asked lots of questions by curious residents as we made our way through the borough carrying step ladders and large yellow signs!.I think our high vis vests reassured people that we were legit (maybe!).

I saw the sign...and it opened up my eyes (apologies to those too young to get the reference!).
