I'm wanting to commute to work (17.5 miles each way), the problem is that my route is along the A628 over the woodhead pass. My concern is how busy and dangerous this bloody road is. My partner is not happy about me using this route, unfortunately it is the only option I have, apart from.........., the trail that runs from Hadfield to the woodhead station. I would then only have to use about 2 miles of the A628 before rejoining the trans pennine trail at Dunford Bridge which will take me all the way into Penistone. I currently have a road bike which is unsuitable for the trail, so I'm looking at getting a new bike through the cycle to work scheme. My quandry is, which is best for this kind of route?, a mountain bike or a hybrid. I'm swaying towards the Mountain bike as I think this will be best suited to the trail part of the ride. My only concern is the road part of the route, about 4 miles in total. Any opinions?
