I do a mixture of the above. During the winter, I either park about 10 km or 15km from work (Lincoln) and run there and back. In the summer, I run home in the evening - 21 miles - then cycle in the next day. I have to wear a suit to work, so I have to be organised and plan days ahead. Fortunately we have a shower at the office. At my previous job I had to use a washhand basin and lots of deoderant.
Rich - do you run for a Lincoln club? I only know of one other ultra runner in Lincoln so it will be nice to meet you at the Dukeries (I've already entered).
I was only smiling for the camera. I crawled up that last hill into Lamport .
Wisdom will come with experience; it takes a long time to become good. But, I like your attitude - "needed ...a tougher strategy".
I've not done the GUCR. It doesn't appeal to me. I'm not sure I could keep going for 145 miles and have no intention of finding out. I did dabble with the idea of attempting the Spartathlon, but at my best pace I would be on the cut off limits all the way round.
