Penny farthing records

After doing a few time trials on the penny I started to look up penny farthing records. The outcome is almost unbeivable. Try this one for starters.. Lands end to John O'groats in 5 days 8 hrs and 15mins! Thats 168miles per day! The record was set by a guy called Alec Baxter and will never be beaten. I say this as firstly I am sure that it can't be and secondly because the Road records association no longer accepts attempts by penny farthings. I can only assume they don't want anyone being killed whilst trying! Other impressive records seem to be less well documented but various people in the know tell me that a penny farthing has been peddled at over 20 miles an hour average speed for a twenty mile time trial. Thats not bad going on a modern road bike, let alone something that was designed 120 plus years ago.
