Doctor Who star Matt Smith swapped his sonic screwdriver for the Olympic torch as the relay began its journey from Cardiff to Swansea on day eight.
He ran an early morning leg in the Welsh capital, where the hugely successful television show is based.
Later in the morning the torch will be carried in Merthyr Tydfil by Welsh rugby player Matthew Rees.
And hurdler Colin Jackson, who in 1988 won Olympic silver in Seoul, will run one of the day's final legs in Swansea.
Smith ran from the historic Norwegian Church in Cardiff Bay to the Senedd just before 06:30 BST.
He said he was "thrilled" that around 1,000 people had lined the streets so early on a Saturday morning to watch.
"It's a great privilege to be involved. I can't quite believe people have actually turned up, I thought I would be just be carrying it around, waving to the ducks.
"I'm really excited about the summer of sport we have ahead. It's wonderful."
A talented footballer who once played for the youth teams of Nottingham Forest, Leicester City and Northampton Town, he had no difficulty covering the 300m.
In a previous life the Doctor, then played by Tennant, went forward in time and carried the Olympic torch in London in 2012.
