If you did the Willy Warmer on fixed you'll be fine on this one.
What you'll find is that you can do pretty much anything on fixed, it's just different from having gears; seems tougher at times but it just comes down to getting used to climbing at lower cadences and big downhills being work rather than a rest.
Thanks for the encouragement. The Willy Warmer was a lot easier than had I expected. I wouldn't say it was 'easy' but certainly comfortable and managed to ride up all the hills even with all the extra (probably unnecessary) luggage.
