A 246km race that traces the footsteps of ancient Greek messenger Pheidippides

These days, it seems like everyone has run an ultramarathon. But Janice Leung Wan-yee is the only Hongkonger who can claim she has run the original ultramarathon.
The 246km Spartathlon race traces the footsteps of ancient Greek messenger Pheidippides. He's famous for inspiring the modern marathon, but it was his two-day jaunt from Athens to Sparta in 490BC to request help against the invading Persians that inspired the race.
"When I first read the history of Pheidippides and found out about the Spartathlon, I was hooked," says Leung, 39, a government worker who took part in the event last September. "There's no major sponsor or commercial intent behind the event; the race started because someone wanted to recreate history."
Runners must complete the journey - roughly six marathons back to back - within 36 hours. Hundreds of runners start; less than a third make it to the finish. "I had to run the first 90km in 9½ hours," says Leung. "I wasn't even sure I would make the time cut-offs until I had run 200km. It was a very emotional moment when I knew I'd be able to finish."
Halfway, runners must ascend the 1,215-metre-high Mount Parthenion (slightly more than double the height of Victoria Peak) and continue on more undulating hills before a long downhill to the finish.
Just making it to the start requires years of training. Leung began hiking in the mountains, then climbed Mount Blanc and mountains in China and Japan. Over the years she gained speed and switched to ultrarunning, completing 100 mile (160km) races in the mountains and finally a 200km ultramarathon in South Korea in 2013 to qualify for the Spartathlon.
