I have ridden in it the for the last three years as part of a company wellness program. They are expecting somewhere around 3,000 riders this year. It is a fun event and you can ride at any pace you choose. The 10 mile ride is very flat and the 25 mile ride has a few inclines but nothing you would call hills for the most part. The 42 mile ride has some hills but not too bad. I normally ride 25 miles but am considering the 42 mile this year. The rides are out and back and there are refreshments at the turn around. You will see all types and ages of riders. I'd be happy to provide you with any other information, just let me know.
