Well I did it! 10 days, the history on my Garmin shows I covered ~850 miles, I've got to take a good look at the GPS tracks before I confirm my actual distance, compared to the planned route. It wasn't possible to take all planned shortcuts due to weather in Scotland.
The route was an interesting mix of main trunk roads and some intricate and interesting & hilly riding through North East Devon, Quantocks, the North west, South of Edinburgh, Highlands, and finally the strange last 20 miles I'd plotted over the middle of the peninsular to JOG, where one road did not exist.
Fascinating experience.
In terms of LEJOG ride in general I made something hard, even harder, I've lost 3/4 of a stone, I think carrying camping gear no matter how light, slows you down a fair bit, I say this as I joined a guy Alex for half day and he was carrying nothing, aerobars, support etc, I think we were about the same fitness but he was able to leave me about a mile an hour or so faster as we approached Edinburgh.
Still I should fly around Hertfordshire now with no 7/8 kg panniers on.
I loved the challenge, the planning, execution and everything about it so a question for the forum - what next..?
What are the similar challenge rides maybe somewhere warmer
