I have no opinion regarding eventual stupidity, but regarding geekness: I was the mechanic at Barnard Castle on the last LEL. I saw many sorts of bicycles in more or less poor condition, but NO recumbent.
There were a few issues with recumbents on LEL.
1: There was a Milan GT on the ride using the stupidly light, flimsy, flat prone and hellishly expensive Conti GP LTD tyres which had to DNF due to tyre problems.
2: Stuart almost had to DNF due to using a weird size tyre which was about to disintegrate and had no spare. Thankfully with a bit of help from Duct Tape it held up just long enough to allow him to finish.
3: Some guy was riding an almost new Birkenstock (costing about £15k). The rider wanted me to shorten the chain, so I removed one link and tried to pull the ends of the chain together to join them however I was unable join the ends as there was a few mm to little chain so I had to put the link back in. I tried to explain this but I don't think he understood me as when he came down southbound he complained I had not removed a link like he had asked. Anyway I had to endure this thing being leant up against a wall a few feet from myself for several hours. It was not locked. It required a huge amount of self-restraint to not hop on the thing and take it for a jolly. I have a feeling the owner would not have been too pleased if he came out to find his bike in bits after I had wrapped it around a tree... Oh and the thought of a £15k bill....
