Rode a 400k yesterday on a totally normal Ultegra triple - 52-42-30 in front and 12-25 in back, so 117-32 inches. It was quite a flat 400, only 5000' climbing. Used every gear except the bottom two. Finished in the 3rd group, about an hour behind Jan's group. Rode Vredestein Tricomps @140 on a Trek 5200. Everyone in my group was on well-pumped 23s. Good bit of chipseal. Lots of upwind work. Due to a combination of the time of day and course, only had about 50 miles of downwind. Finished in 15:03 with an 18.8 in the saddle average. I'm no athlete, just a below average 8 minute miler in my youth (now 61). So I'd say that combo worked well. No complaints this morning, other than it made more of a mess of my already bum knee and my legs are really shot today.
The hero of our group was a guy about 25 who rode the whole thing on his fixie. He was (no surprise) even worse off then me during the last hour.
