Last Saturday I run my third Midnattsloppet in 50m52s (10 km). It was the fastest I have ever run I guess and since last week I did not feel very well I'm very satisfied. I had some problems after 7 km where my stomach was giving me some problems but after resting for about a minute I could start run again.
If I use the results of the previous years I can see that I've been improving my running quite a lot:
I think I can now start practising for the Lidingöloppet, which is 30 km and much harder. But at least I feel well
