This morning I had to run in the rain, which is actually quite pleasant. I had carefully chosen my route to give me the right sort of time & distance, and had set off with just enough time to finish it before church, i.e. maximising my lie-in. The last 500 yards or so the plan was to cross the river over the road from my house. If it's dry, then you can walk the 5 yards or so across the weir, or if that's a bit deep, then hop across the stones. Since it's been raining for about 5 days on and off, the stones were underwater, so I had an unscheduled detour, adding about 2km to the route - and only that little because the wife came to look for me.
If that's the worst mishap during my training, then I'll be happy.
