Scottish Cycling confirmed the death of a former employee who set a new record for completing the West Highland Way in 2020.
We send our love and support to his family, friends, and all those in our community who knew him, even though we have very little information at this time.

The Scottish Cross Country Association said Wardell's death was the most sad news.

He will be missed by all of us and his determination, talent and friendship will live on in our memories.
