I've put my (£5000 if you don't mind, Mr. Teef) bike in the hold of a coach coming back from the Dunwich Dynamo. Steel bikes to the bottom, a blanket, carbon bikes on top, lots of bungee (sp?) straps. People of a nervous disposition could wheedle their bikes in to the van. Wheels would go on the back seat of the coach (or suspended over the frames in the van), and luggage would travel in the seats. Note to self. Why is there a boy in my daughter's bedroom this morning? As you were.
I'm grateful for Stuart's post, but I'm not going to make any one way back compulsory or close to it. I think, having talked to the coach company, that we would be back in London before 9pm on Sunday - although I appreciate that people might have a way to go from there. The van and the coach would travel to the same point, and the bikes from both unloaded - probably by the boy in my daughter's bedroom if he wants to keep his head on his shoulders. If people have to get back south earlier, then the clever thing to do would be to fly, but there would be the option of transporting the bikes (for money) in the coach or the van. I'm not, however, contemplating taking the coach out of its way to Inverness Airport. For you, Stu, the train and bus beckon.
There's also the second van option, which seems expensive, but at £25 a bike it's cheaper and (dare I say) more reliable than postage. Oddly - the price of the van is bumped up to £444 by VAT - coach travel is zero rated.
I do think that if the second ride joins us we will get sufficient to make the coach an economical option. Unfortunately the second ride is being masterminded (ha) by a delinquent teenage BMX rider who thinks nothing of posting pictures of girls in bikinis on these very boards. If I discover that he is the boy in my daughter's bedroom then he'll definitely be doing the Beacon standing on the pedals.......
