Two-time world 400 metre champion Christine Ohuruogu is the latest athlete to confirm her place at the Great North City Games in September.
Ohuruogu, the 2008 Olympic gold medalist in the one-lap event, will run in the rarely-competed distance of 500m at the Games in Newcastle and Gateshead.
Joining Ohuruogu in the event will be fellow Englishwoman Jenny Meadows, as well as Scottish duo Lynsey Sharp and Eilidh Child.
It will be the first time the quartet have raced over the distance, and should be an intriguing encounter, with the four athletes specialising in three different events between them.
Sharp and Meadows, the two 800m runners, will test their speed over the shorter distance, while Ohuruogu and Child will be stepping up from the 400m and 400m hurdles respectively.
Ohuruohu looking forward to event
It is something Ohuruohu is certainly looking forward to.
"I love the CityGames events but this time in Newcastle I don’t know what to expect," she told Athletics Weekly. “I normally race one lap of the track, so racing 500m will be a completely new experience for me. It is going to be a lot of fun and I will give it my best shot."
The current world champion in the 400 flat, Ohuruogu has taken 2014 a little easier, though she still managed to win bronze as part of the women's 4X400m relay team at the Commonwealth Games.
Child won silver in her event in Glasgow, and went one better at the European Championships in Zurich, while Sharp finished second in the 800m in both.
Whoever comes out on top, it is likely to be an enthralling race come September 6.
