OK, it didn't leave us completely unscathed and it was a bit tough – but it was worth it: beer has never tasted as good as it did after those 30 kilometers! After a “trial run” in Hanover with a smaller group, we did the Duisburg Little Mammoth together in April. We've already forgotten that we couldn't even walk back to the car afterwards, and we're already thinking about signing up for the next one.
