I participated at the running group this evening at Sportanlage Süd. It was the second exercise/ session today. The organizer is a company started by the former German Ironman (Iron woman) Katja Mayer. I got a blister, it actually started yesterday when I ran 10 kilometer but it became bigger today. I ran in the fastest group like last week. We run 8 km interval, 1 kilometer slower and the following kilometer faster. We also had some technique exercises. It was nice to come out and meet new people.
