Aston Clinton U3a have invited any WTu3a members to join in with their Strollers walking group on the 4th Thursday of the month at 10.30. The walks are quite leisurely, only 2+ miles, lasting 1 -1.5 hours, and try to avoid hills and stiles.
They usually have coffee afterwards if there is somewhere close by. Contact the group co-ordinator, Jane Hudson via the Aston Clinton web page, or this link.
