From the Subway Saturday site:
"Oscar and Michael Sheridan are proud to announce that the challenge has been run and won. Every line and every station on the Beijing Subway. All in a newly minted world record time of 14 hours and 24 minutes.
From International Exhibition Centre at 05:37 this morning and finally back to our beautiful home station for a pass through the turnstiles at 20:01.
Couldn’t have done it without our supporters. Or without the excellent value that the Beijing Subway provides.
What’s next? Stay tuned to subwaysaturday.com Who knows what we’ll think of next…suggestions are welcome. Challenges are fun!"
