However, one time I has GI issues and had to stop for an emergency bathroom. Embarrassing. Then later I pulled for like 20 minutes (for fun and to keep the pace up). But then on the same ride my rear derailleur cable broke. Felt pretty bad to have 2 issues on one ride. I would not have minded buying a round of coffee if that's where we ended up. Even though I already had the embarrassment penalty AND the finish the ride in my 12t cog penalty.
