Enter our competition to win a set of Schwalbe London tyres

Following on our exclusive test of the new Schwalbe London Durano Plus tyre, the good folks at Schwalbe have given us 10 pairs of the even beefier, even more puncture-resistant for a free-to-enter competition.

The London Marathon Plus has a flexible rubber SmartGuard layer beneath the tread to prevent punctures, but that doesn’t stop it being an easy-rolling tyre for either town or country use; the new model also has a refl ective London skyline logo on the sidewall.

We’ve got 10 pairs to be won, in 700 x 28c size — suitable for most road bikes and similar-wheelsize hybrids.

All you have to do is answer this simple question:

How many people attended the Big Ride in April? (to the nearest 1000)
