Mike, I like your thinking.
I was supposed to be doing the Darlo audax this weekend, but can’t in the end (shame, with this lovely weather). Could be up for your route sometime later in the year if you fancy trying it out and sharing the knowledge.
I’m getting a cx bike on C2W soon, so will be hitting some longer rides this year. I’ll stick details up if/when I do them. Hoping the geared cx makes 100 mile road/dirt rides slightly quicker than the SS MTB I’ve been using 🙂
Also thinking of Darlington to Whitby along the Sustrans W2W, for fish and chips for lunch on the pier, then riding back. And nipping to Dales Bike Centre for a morning coffee will hopefully become a staple ride 🙂
