Reckon sunrise will be about 7.00 ish by March? Anyone got a better educated guess?

If it is 7am and your start time is roughly between 11 and 12 then you would be around Bleaklow area maybe even as far as snake pass if you are in the middle of the pack. These are very rough estimates by the way.

Check out last years results for a guesstimate or schedule for recce's
