Who is fitter? kmfm breakfast presenter Garry Wilson or kmfm drivetime presenter Rob Wills?

If you can guess the answer, you could win a new mountain bike.

They DJs have taken on the Cyclopark cycling, running and spin fitness challenge at the Gravesend venue on Wrotham Road.

The pair both cycled the 2.9k metre race track on a mountain bike, ran 800 metres around the race track, and took part in a two minute spin cycle.

To take part in the Cyclopark Challenge, you need to text ‘Fit Garry’ or ‘Fit Rob’ which corresponds to whoever you think won the challenge, to 87474.

Texts are charged at your standard network rate.

The competition, for a Claud Butler Criterium 14 speed mountain bike and 30 minutes track time at the Cyclopark, closes at 5pm today (Thursday).

Entries before or after these times will not be accepted.
