I had the dubious pleasure of negotiating a mile of Route 4 on my road bike with 18mm tyres this
morning - railway ballast and deep sand seemed to be the order of the day. Are most of them like
that, and if so, why can't Sustrans be more upfront about the fact that they're MTB-only (I wouldn't
even have wanted to take my expedition tourer down there!)
I read the C2C booklet last month and nowhere does it mention that "proper" bikes are unsuitable for
completing the route. Sorry guys, but the NCN isn't going to be anything other than a weekend
leisure activity unless you can get some blacktop out there. Most people like to have mudguards and
road tyres on their commuting bikes!
On the other hand, the tarmac path from M4 J16 to Swindon town centre is nice...it bypasses a piece
of 70mph dual carriageway, which in itself wouldn't be so bad if there weren't wheel-eating drains
every 100 yds :-)
