The Thames Path follows the River Thames from its source in rural Gloucestershire to beyond the Thames barrier – almost 200 miles in all. My plan is to do it all in 4-5 stages. The first stage, from Kemble to Oxford is around 50 miles and I start that on Tuesday 17th September. hopefully getting to Oxford on Friday 20th. I shall be staying in Kemble, Cricklade, Lechlade, Newbridge and Oxford. There is more information in a blog by Keith Palling, who walked the path in 2007.
Kemble is a small town in Gloucestershire, and is the nearest settlement to the source of the Thames at Thames Head. Trains go to Kemble station, from Nottingham, change at Gloucester, takes about 3 hours. I am staying at the Thames Head Inn, and they helped me book a taxi from the station with A-B Taxi (01285 655 651).
