I'm planning a century ride with a buddy of mine and as we're trying to plan a route to take, we're here in the UK so I don't suspect many of you will know about routes here but I wanted to get your advice for what makes a good century?
Is flat better than hills, flat might be easier but maybe boring?
Is it better to go and come back, or do a big loop?
Should we plan in some scenery?
What things would make my 100 miles more fun?
