I really want to do the Lake Pepin tour and you have to do that on a 3 speed:

People have been riding 3 speeds for a long time over all sorts of distances. Records for different rides were set in the UK riding bikes with SA hubs; the most famous of these is the Raleigh Record Ace which was used with a SA 3 speed hub to set the record from Land's End to John O'Groats in 1929. The ride was ridden in 61 hours and 27 minutes. That's around 840 miles with a lot of climbing.

I have a 1950s era Claud Butler Jubilee that I plan to build up with an SA 3 speed and drop bars to do some longish rides.
