It was not like that the entire time, only in a few sections and that was the worst one above.
As soon as you hit a puddle, and we are talking about a pot of beer puddle, you have no grip and I mean 0 grip, untill the tyre drys off after a few revolutions.
To get through the above pic, we basically walked the bike with it just spinning and providing no drive. It was a funny situation, cos the way home was just in front of us and there was no other way around the water, other that to head about 90% back the way we came. So we went for it!
