THE annual Marie Curie Cancer Care go-kart challenge has proved more popular than ever, with all places for the race filling up so quickly that organisers have decided to add an extra session on the track.

Teams of six can now enter the evening challenge on the Shenington Circuit near Banbury, where both David Coulthard and Jenson Button started their Formula One careers. The event will be held on September 9

The entry fee for teams is £240, which is inclusive of a sponsorship fund for Marie Curie Cancer Care.

Anybody wishing to take part should contact Piers Roache on 07980 474249 for more details or email at piers@roache.freeserve.co.uk.
