I would be interested. I too live in Maidstone. I'm 47, working on getting fit, and have a fairly regular cycle route I use which equals approx. 20 miles. I had planned on doing it every day but work took over, however I do try and go out in an evening, around 6pm.
Where in Maidstone are you? I am on the horrible Ringlestone Estate.
My cycle routes, are - Ringlestone, through the park, up Buckland hill, along college road, then down towards East Farleigh bridge, up the hill and continue up hill towards Linton, through Linton, all the way through until you get to the crossroads (straight on leeds) turn left, and head through Parkwood back through town and home
The other route I do is, Aylesford, up through Larkfield, Kingshill, wateringbury and Maidstone.
I'm not great, on flats I can keep a 16-19Mph pace, on hills (long hills) I'm around 8mph (could probably push it to 10) and steep hills, I go backwards
