terrain run intervals 13:00  2.63 km (4:57 / km) +75m 4:20 / km
Witch's tower approach
The course is a little bit longer than I previously thought, so I am going back and editing the previous sessions.
15 x 175m with 30-50s rest
47-56s each with most between 49-53s
The shorter rest caused larger variation in time as running too fast on one made me tired and slower on the next one.
