Running intervals (Cruise intervals) 30:00 [5] 7.3 km (4:07 / km) +15m 4:04 / km
shoes: Mizuno Wave Rider
3 x 2km on a 10 minute cycle (aim was @3:35min/km but ended up just above 3:30min/km).
Tough session and was a little worried about the tendon issue but turned out ok. My guess is that it was the soft sand I was running on as well as me being very active throughout the rest of the day, including kneeboarding which I wasn't used to. First was full into wind, second with a tailwind and 3rd with half of both. Struggled on the 2nd km of the 2nd one and then had to push hard in the last. Times were:
6:57
7:01
7:04
