Felicity Rees is running this 10k through the heart of central London, in memory of her son Mark. You can sponsor her here.
Felicity writes: "I am running in memory of a much loved and greatly missed, kind, intelligent, loving son, brother and friend, Mark Anthony Halsey. Mark died suddenly and unexpectedly in September 2012. The Compassionate Friends are an amazing group of people who have been there to offer support, kindness and understanding when it's been so desperately needed.
You can join Felicity - we have more places available to run this fabulous iconic London route. It is a great day out in a friendly and supportive atmosphere and, even better, you can raise funds for TCF!
For more information or to reserve a place in the run (usual entry fee £50) contact us at email@example.com or on 0345 120 3785 by the end of June 2016.
Each year thousands of parents suffer the loss of a son or a daughter. Please help us to support families in their time of greatest need.
