Running 18:19 [5] 4.87 km (3:46 / km)
4x1217m intervals in 4:31, 4:34, 4:37 and 4:38. Decided to do these in heavy trail running shoes so arguably these are equivalent to faster times recently in lighter shoes. Surprised second one was slower than first though - I felt like I was working through lots of stiffness from the tag on Sunday in the first one.
