'The' Yaztromo
For me... it has to be Richard 'running through treacle' Barker. I watched a breakaway featuring 'the bear' at Darlington back in the day, and everything went in super slow mo... I'm pretty sure dry ice covered the pitch too and alas I saw it all in real HD his legs were pounding away but he seemed to turn like a combine harvester stuck in a back alley and accelerate akin to a hardback book sitting on a bookshelf.
