I can report that Eggy is alive and well and actually pretty chuffed with his run this morning.
Loch Katrine was great, but also brutal. Stunning route to run along. It really is one of the most scenic parts of Scotland. The loch by your side, fern covered hills all around and snow covered mountains in the background. The downside is the loch road is hill after hill after hill and once you've done that they throw in another hill just in case you hadn't seen enough of them yet!
I finished in 1:53:36, which is way better than I expected. It's 10 minutes slower than my PB, but Loch Katrine is a far harder course and I felt I paced myself well for the hills and injury management. Felt a little pain in the groin in the closing miles, but nothing too bad.
Conditions wise it was bloody freezing and very windy. It started snowing on us at the start line, then was sunny, then started snowing again. It was headwind all the way back from the turn point too. Why is it always on the way back and never out?
Feeling good about the run though. Mentally that's a big plus for me. All my long runs have been pretty hellish this year and I felt good today, if a bit tired with the training miles of the last few weeks in the legs. It was nice to go and run a good distance and really enjoy it again. Plus a Tunnocks caramel log at the finish makes any run worth doing.
