Tomorrow's ninth Tokyo Marathon on Sunday (22 February), will feature the use of the world's first 'edible wearable'. Fruit and vegetable company, Dole, has created a GPS-powered banana which uses an LED to show race times, heart rate and messages of encouragement from spectators sent via Twitter.
The banana is connected by wire to a separate device that the runners carry. Once the race is over the runners will be able to eat the banana.
A Dole spokesperson said: "The banana will be peeled first to remove its content and then resealed after a LED display and a smaller banana is put inside."
It's not the only fruit-themed device featuring at the event. Japanese juice maker Kagome has unveiled the 'Tomatan' - a hands-free tomato machine. The humanoid-looking backpack can be loaded with six mid-sized tomatoes; enough to power runners through today's 3k fun run.
The men's marathon will see defending champion and course record holder, Dickson Chumba take on multi-major winners Tsegaye Kebede and Geoffrey Mutai, as well as Olympic and World Champion Stephen Kiprotich.
Three runners with PBs faster than 2:23 will line-up for the women’s race plus two marathon debutantes are worth watching. Contenders include Berhane Dibaba who came second in the women’s race last year, setting a PB of 2:22:30, and Ethiopian Yeshi Esayias who has a personal best of 2:24:06 and was second in both 2013 and 2012. The race will also see world half marathon bronze medallist Selly Chepyego, who has a 10,000m PB of 31:22.11, making her marathon debut.
