Hi guys looking to do the callander to killin in May for cystic fibrosis in May.I was wondering if anyone has done this route and what tyres you can get away with eg - road tyre 28c, marathon plus 28c or a treking tyre 28c or is something bigger needed.I believe it is a sort of mixture of gravel paths and roads,but if anyone can enlighten me to this route it would be highly appreciated thanks
