The roar of ice and snow so loud you can't even hear the shouts and laughter of people right on your wheel. The cracking, crackling whump of thick ice as you try and wheelie a solid surfaced puddle. The held breath, awkward body angle, barely balanced slither across polished glass surfaces of tarmac corners or glinting white ice snow. That's how we've been spending the last week anyway and it's an absolute blast.
Our local trails have never been so solidly frozen for so long, and we've never had more use out of our Schwalbe Ice Spiker tyres anyway. So who care the chillblaines on my toes are as red as Rudolph's nose or kneecaps, hips and elbows are bruised from sudden smashes into the ground when traction has suddenly vanished.
Even if your car is snowed in, grab your bike and go play in the snow. It's way more fun than sledging any day.
