I did not see any 50+ jerseys so they must be sill quite rare. I wore the jersey last year for the 100 mile. That was 25 lbs ago - and it would have been too tight. This year the 100 kilometer was harder even without the killer wind. I had a new rider with me who would not draft so we worked harder to complete the ride. The weather was the best I've encountered at the Seagull.
