Testing orienteering technique to the limit for 40 years and counting. The day you nail it at C-a'-B is the day you've finally cracked the game. I'm still waiting for that day!
Really enjoyed how challenging the course and route choices were. Just need to get the fiddly bits right! Well done you on a clean run.
Not clean, but only slightly grubby, better than my usual Mud Bath :-). Like you say, you got it 90% right - just need to work on those Traffic Lights more, from the sound of it. I don't need to bother with that, since I'm on flashing amber the whole way!!
