In a one-off race at Scotland's premier Kart circuit Martyn makes a comeback in karting.

Racing a Gillard Formula Blue, courtesy of Saltire Racing Martyn will join in the fun in the season finale.

We hear that many other non-regulars will also be racing- Staven Napier, who is a regular froint runner in the National classes as well as David wagner will take on the regulars, including the British numbers 1,2 and 3 as well as the O plate champion.

It's around 18 months since Martyn last raced a kart so it will be hard going but he is really lookin forward to it.
