7 am start from King's makes for a relaxed second day, even for a full-value rider.
Wise words Somnolent
Yes, when riding with groups that was always seemed to be the popular departure time. As you've mentioned, a relaxed 200 in 15 hours
I've usually rocked up to there sometime around 4 am, as beds start to come free.
Turning up as the beds start to be ome free has benefits all 'round. You can have as much bedtime as you like, demand for beds tends not to exceed supply. Helpers then spend less time going to & fro from dorms.
An hour eating / faffing and a couple of hours sleep seems to work OK for me, although I am always abysmally slow on that long climb past the Cross Foxes.
I don't think that many fly up that climb Peter. What really helps is a tailwind, if you can feel the wind on your back as you go up past the petrol station, just pray that it holds for the next hour, you'll get a real boost for the upper stretch.
I always used to "allow" myself half an hour to get to cross foxes, and another half to crest the compleat climb. The most 'unwelcome' bit being the downhill bit just after cross foxes to the farm. It's the last thing anyone really needs. If I took less than an hour - great, if I took more - no big deal, just use the following downhill to best effect.
For me the road mods between the Brithdir turn and cross foxes is an improvement. Getting rid of the niggling give & take inclines helps keep a good rhythm.
