About Us

Sue and Den have lived in Harrow for over 20 years but have only recently realised the great potential for improving health, fitness and well-being by exercising outdoors in them.

Sue Collen

Sue and her family have always been involved in Sports and Physical fitness - for the sense of achievement and well-being as well as fitness and fun. She was a keen netball and tennis player, but after two ruptured achilles tendons and the beginnings of arthritis in her knees, Nordic walking fitted the need to keep exercising and be outdoors at the same time.

Originally trained as a head of Biology, Sue then qualified as a counsellor and coach and spent many years supporting young people with social emotional and mental health difficulties in schools. With more time on her hands now, Sue discovered Nordic walking and the joys of exercising outdoors whilst making new friends and connections in the community.

She trained as a Nordic walking instructor to be able to share this new found passion with others in the Harrow Community and looks forward to you joining her on one of her regular walks.
