There was an incorrectly located control on both the H1 and H3 - not sure about the H4 - so you'll have to add ten minutes to your time like the rest of us :-)
Or take 10 off Anthea's which would make her time even more impressive.
I don't think the H4 had that control anyway but it's amazing how much faster I go when I don't have to visit the control!
Yep much easier without real controls out
