Hike 4:16:08 [2] 15.8 mi (16:13 / mi) +1265m 12:59 / mi
Seems to be no issues. Later on in the walk, I could feel that the (left) calf was working a bit more, or a bit weaker. More so because the good one was completely fine with the exercise. 15.8 miles in 4h 15 mins, with nearly 1300 metres ascent/descent. It was a mix of gradual and steep uphill. No problem on downhill at all.
