Ulven course: Treshold session

A good day running. My aim was to run sub 5 for a period of around 20 minutes and that I managed. A bit rainy earlier today, but weather was good when I ran in the evening. A great deal of humidity in the air. Didn't take long before the sweat bursted out. I can feel very clearly that my average speed is increasing. That's a good feeling. In the weeks to come it's important to establish a higher working pace on longer runs. My aim is 5. It's a tough standard, but what the heck, I need some hairy targets. Running at 5 I'm able to run a marathon at 3:30h. That's my main target this year. In Stavanger in two weeks I'll target for sub 3:45. In Berlin a month later my aim is 3:30h.
