@theboxers - thanks for the link, I'll certainly give that a whirl through the winter. Since I retired last week I have been out and about riding locally, and just doing the league rides on the turbo.
Mrs GW has prioritised my list of jobs, so not too sure about all this free time, but at least I don't have to
cram everything into the weekend, which would be a problem now that footie season has started.
I'd been keen to hear how you get on with that Rio course as that's next on my list for later this week.
