I'm a 2 ping man myself... Maybe I should experiment with 1 ping only, see if that suddenly makes me more competitive ;-)

Of the 3 groups of friends of mine that tried the D class, 2 DNF'd as they didn't even complete Day 1 (well they got to camp but by missing out loads of controls). If I remember correctly they said the distance from Cp1 to Cp2 accounted for over half of the distance for that day, which they felt wasn't right - made it boring. Day 1 was also apparently 27 km with massive climb. They walked back down the road to the start in the morning of Day 2 and went home rather disappointed.

My mates that finished though, came in 5th place :-)
