So, after the first run and a full day of Christmas shopping I came down with some serious muscle ache. Nonetheless, I went out for a run (after reading online that once you're warmed up, it wouldn't hurt).
I changed my route slightly so that I ran uphill in the beginning, had a large more or less level piece and then turned around. This worked really well.
With Christmas around the corner, I'll finish week 1 here and start week 2 back home in the Netherlands. Looking forward to the change of scenery.
