I took it easy for about a 10th of that
When I picked mine up from an HPC their GTR Tech said to get the oil warm then build up the revs over a few increasing runs. Worst thing you can apparently do is to sit at the same revs and part throttle a lot with a new engine. That can be worse than anything that can happen giving it a good ragging when warm. Main thing to watch is the tyres and brakes. They both need a bit of bedding in before you can fully lean on them, and IMO this is why they impose these running in periods - purely to stop people ragging a car they dont know and trying to nail it on the manufacturer.
My car has now done 15k miles, hasnt missed a beat and hasnt used any real amount of oil.
hmm this could be a problem !!
the run home is 50miles of motorway and dual carriageway, I ve then got a 2 weeks of normal motoring that I can be, lets say flexible, then I've got another run upto Stratford upon Avon at the end of October - so on the whole at the start there's going to be a lot of same revs/part throttle
