First SS1000

Hi all, I have been planning for doing my first SS1000 over the past few weeks. I now feel I am as prepared as I can be to attempt this, bikes ready, routes in two sat navs and more importantly I feel ready. This weekend the window in the weather is looking very favourable, so I think I will give it a go.
I am using the RBLR route going anti clockwise north, picking the route up starting at Carlisle. I will be leaving at 22.00 hrs on Saturday so as to get the motorway section going down country in the dark, which I prefer.
Instead of using Squires as a point is it ok to use a filling station at Park Rd, Castleford WF10 4RS ?
I have Spotwalla and Bubbler working so will also be using this to record the route.
If there's anything else I have missed let me know.
Thanks again.
