Had no idea how this would go, but felt ok warming up. Did some sprints to get HR over 120. Pace judgement was important and I focused on relaxed and comfortable through first lap. Was ready to ease back for second and third but felt fine gradually picking off other runners. Splits were 4.15, 4.30, 4.30, 4.27. Felt much faster than an average time suggests, but I'm pleased to be comfortably sub-18 mins again. Average stride length 1.4m, and max cadence 189 spm.
