Well, not such a daft idea after all.
My clubmate David and I set off at 9 on Sunday morning and finished about 1018k later at 11.21 yesterday.
We had three days and a morning on the road, with six or seven hours off the bike each night, with a shower, a proper bed and clean clothes. It meant we had to keep up a decent pace on the road, which was sometimes made difficult by strong westerly winds, but plenty of food stops, fairly familiar roads and no big dramas made it a generally relaxed affair.
Sunday was a loop up north to Aberdeenshire then back down the coast to Carnoustie; we went west to Tyndrum on Monday then back to Kirriemuir via Callander and Dundee; Tuesday was south to St Andrews, out to Crieff and back via Perth, then a quick outing eastwards to Auchenblae and back yesterday morning.
Many thanks to David for being his reliable, unflappable self throughout, and to Megajoules for helping put the route together. Full report may follow, once I've had even more bacon sarnies and a snooze during this afternoon's stage of the Tour.
