I didn't make it. I made it 52km.
It is with a heavy heart that I have to announce that I have "retired" from the 100km walk. I made it 52 km, which is further than I have ever walked in a day before. I could sit here and blame the rain and headwind, which was not fun at all, but in reality the rain has stopped. The reason I have to quit is that my pace was way too slow and I was about to "timed out" at the next checkpoint. So I opted for a warm & cozy convenience store to wait for a ride home.
The reason my pace was so slow was that I did zero training for this event. I have been nursing a bad ankle for a number of months and was trying to take it easy so that it wouldn't swell up during this event. The good news is that my ankle is doing fine. The bad news is that my lack of preparation left me woefully unprepared for the necessary pace to finish this event. That was a big mistake on my part.
Thanks to everybody who supported me. I will do some proper prep and try again in the future!
