I did what I've been planning to do for a long time, went into the Grunewald forest, ran around the lake and further to where this pic was taken, the Havelchausee which looks like a lake but is actually an arm of the Havel river. It was pretty darn tough being a lot hillier than what I am used to so became my first real run-walk. I ran some hills and walked a lot of others, had a break at this little beach and paddled a bit which the feet loved.
On the way back I followed (!) an octogenarian club of Nordic walkers who gave me an encouraging cheer when I eventually overtook them running uphill. In all it was about 3 hours but I couldn't say how much of it I ran. Am sure the uphill walks were great training for my legs, the sun shone, folk were friendly, air was fresh. Beats the couch any day (although I am there right now!).
Got told off by an elderly gent for walking up the final steep incline. He said, c'mon run! I'm 93 and if I can run up it so can you! I told him he'd had more practice. Hat off to him,running up that hill at 93 and still enough breath left for a bit of cheek!
