Sometimes you have those days where nothing is happening.

There is nothing in your legs.

Your head is telling you it’s silly to try, but your heart feels like you should give it a go anyway, just to be sure. It takes me a while to get going some days and I’ve had some brilliant runs that have started very badly, so for me it’s always worth pushing on in these circumstances.

My legs felt so tight they could snap at any moment. I had stopped to stretch them off a couple of times but nothing was helping. My head was fuzzy and I could happily have closed my eyes and curled up under the nearest bush for a long sleep.

I got 3.5 horrible hard miles into my 20 mile run on Sunday , decided this was utterly futile and so I turned round shortly after I passed the 10k tree and headed back home. I managed to run 1.5 miles on the way back, and then I gave up and walked the rest.

I felt rather silly walking along with my running pack on, but I carried on listening to my podcast and the time soon passed. I’m always amazed by how quickly I get cold when I’m walking in my running kit, and I was glad to get home and feel the warmth of my dog as he greeted me at the door.

Two days later, two whole days with no running, and the bounce has returned to my legs at last. I’m ready to run again and I only have a handful of short runs left to complete before I head out to Switzerland for what might just be my biggest running adventure yet – the Eiger Ultra Trail, the full distance E101 course.

Skye feels like it was years ago and yet only 5 ½ weeks have passed. I’ve still not finished my race report (sorry Jeff, it is coming honest) and I’m still processing everything that happened in those 22 hours and the days either side.

I think I’ve recovered at last and my blisters have all healed, although the skin is still dropping off my feet. This is something new and something slightly alarming – not painful, just a little strange.

I’m apprehensive, nervous, excited, a whole jumble of different emotions, but probably the biggest one is,

Have I underestimated what lies ahead?

As ever, there’s only one way to find out.
