Olympic champion Mo Farah says he will return to the track and wants to defend his 10,000-meter title at next year's Tokyo Games.
On his YouTube channel, Farah says "I'm really excited to be competing. I'm back on the track."
Farah won the 5,000-10,000 double at both the 2012 London Olympics and 2016 Rio de Janeiro Games. He switched his focus to the marathon and road races after a farewell 5,000 victory in Zurich in August 2017.
Farah won the Chicago Marathon in 2018.
The 36-year-old British runner says "I hope I haven't lost my speed."
