This little gem is proving a great alternative to roads as a route to my cyclo cross riding areas. The Grand Union is less than 1/4 mile from my front door. If I turn right I can cycle it to the start of my Woburn ride. If I go left it'll take me to the Beacon and Ashridge or a little further on and it'll land me near Wendover and the home of Aston Hill. Tempted to get the Kayak out on it.
