I did my Outwoods reps today (lunchtime, so I had the bright sunshine between the trees to my left): slightly longer and steeper than yours (0.3m, 150ft). Like you, I felt awful on the first rep, but was shocked to see how fast I had done it (2m42s). Unfortunately, although I felt much better on reps 5 and 6 (the last two), the times were much slower (2m51s and 2m53s).
