Yep - I did it last year.. it was very, very windy!
But its a lovely friendly run, pretty flat terrain along the seafront, and there would be no problem even if you were last - you'd still get lots of support.
I did 1 hour 40 last year - which was quicker than I anticipated, so I reckon you'd get under that 2 hours
Would love to do it again - but am doing the Luton mara relay on the same day
And if you like the 10 miler...there is a 20 in March...I did that too!
