Sounds perfect in terms of conditions, just glad it wasn't this weekend just gone.
Mrs J's parents live in Seaford so planning to come down Saturday, stay the night then drive over in the morning (saw that the train station is offering free parking) so will park there and aim to get down to the start for 8.30ish. I actually hate going into the pens until the last possible second, I'm always a bundle of nervous energy before a race and prefer to not be around loads of people.
Will keep an eye out for you though...
