While on holiday many years ago we were sitting around in the late afternoon and someone asked "what’s the time?" The answer he got in return was "Wednesday, I think!" This pretty much sums up the attitude of the riders in this race. The important time is sunset.
After sunset the portages are impossible to get through. We then have to plan a later start for portages out of support stations, or really early ones to get to portages at first light and then into support stations before dark. This is the reason for the lead changing hands so often, because the placement of portages can trap people at the stations overnight allowing others to catch up.
