I crew / pace a lot of hundreds and it is like going to Ultra Grad School. One thing I see  experienced hundred runners do over and over is get 24 Hour Fever.

Coach Andy

• The worse cases I saw was at WS 100 where everyone in the race has done a fast 100k at least.
• 24 Hour Fever is from the very start pushing just a little too hard, not taking enough time at aid stations to take care of yourself and just having the 24 hour splits on your brain from the start.
• Just being a little frantic and trying to gain seconds early on that will cost minutes later on.
• There are so many ups and downs in 100s that you don’t need to add to them by worrying about hitting splits etc
• Just take what the day and the course gives you and then when you get to 75 in good shape, then go for your sub 24.
• Wizards don’t have a pacing plan because 14:24 pace isn’t that fast if you pace yourself and take care of yourself. I have never seen someone MATH themselves to a sub 24 hour but I have seen them MATH themselves to a barely make the final cutoff.
