My strategy last night was Road to Sky - did the first flat 10 minutes to the bottom of the climb on the TT bike, swapped to the Aethos for the climb, then swapped back to the TT bike for the descent, so 20-25 minutes of TT bike time and about a thousand metres of elevation toward the climbing bike.
Started the climb inteding to just go at a steady medium pace, and then realised about halfway up that I was on target for a sub 1 hour time so my competitive side kicked in and I ended up having a much harder workout than I intended at the start!
