Running tempo (Terrain (coast)) 40:12 [4] 9.0 km (4:28 / km) +30m4:24 / km shoes: Mizuno Wave Rider
Another attempt at a longish run (this time 80 mins). Felt the tendon again so cut it short but judging on the lack of pain the next day it was most likely in my mind or I stopped at the right time. Taking a rest day tomorrow just in case.
