London - Britain's Mo Farah is confident preparations for this year's Olympic Games in Rio remain on course.
Farah will run in the World Half Marathon Championship in Cardiff on Saturday as he continues his build-up to the defence of both the 5 000 metres and 10 000 metres Olympic titles he won on home soil at London 2012.
"Training has gone well, I'm pretty happy how it's gone," Farah said told a press conference in Cardiff on Friday.
"Rio is looking good and, as long as I can stay injury-free, I should be good for Rio.
"I'm really excited to be competing here, it's part of my journey to Rio.
"It was a no-brainer to say yes to this race because I love the support of the home crowd.
"Ever since I ran at (London) 2012 in front of 80 000 people I want to run at home.
"It's going to be a tough race, but hopefully having the home crowd behind me will make a difference."
Not for the first time in his career, Farah is set to have contend with group tactics by a posse of Kenyan runners on Saturday, with defending World Half Marathon champion Geoffrey Kamworor leading a strong contingent on the streets of the Welsh capital.
"A lot of things will be happening tomorrow," said Farah. "When it's a longer race and there are more people in the team then you can work better.
"So it works to their advantage - but I'm a lot more ahead than I was last year. I always set goals and targets and I want to get a good result.
"It's a chance to win another title and come away with a win, but the target for all of us this year is Rio."
