On the way to my 2nd ever triathlon I had my bike on my rear rack and I missed the turn but thought "no problem, I'll just go down a mile and take the grid road back" so I did, after a rain on a gravel road.

Of course I unloaded my bike and Duhhhhh the rims and tires were covered w/ gravel grit. Luckily someone had some paper towels and I cleaned it off best I could, still not thinking of any repercussions from it.

I made it through the tri, made it home and went on the club ride but 15 miles out of town I had a flat. However, I know how to time it! Our main LBS wrench was riding that night and changed it for me saying " hmmmm that is strange you have a lot of gravel caught in here" La de da de da
