Wall Street Journal reporter Adam Thompson has wrapped up a unique biking challenge, completing a tour of all 702 Citi Bike docking locations across Manhattan.

Thompson said he was particularly surprised to find how quiet some areas of Manhattan can be, highlighting Tudor City in particular.

“I found a lot of places like that that were surprisingly quiet, surprisingly green and just little oasis in a very loud chaotic place,” he said during an interview on “Mornings On 1” Tuesday.

Thompson said he started the endeavor as a way to get more exercise and made the biking challenge a part of his daily routine, breaking up the visits to each docking location over the course of several weeks.

“Some of it was just to get out, get fresh air but also, I wanted to get exercise and the bikes are so heavy that actually became a plus for me because it was just extra work and that was OK,” he said. “Most of the time—except for a few of the toughest hills.”

Among his favorite stops was Highbridge Park.

“I definitely want to go back to in Inwood more, I kind of really like Highbridge Park. I found that to be fascinating. Up in Washington Heights, there's a bridge there called the Highbridge—which is I think the oldest standing bridge in New York City from 1848—and it's got a pedestrian walkway there. It's beautiful. It just has a lots of lovely spots like that,” he said.

Thompson recommends cyclists looking to undertake the challenge be aware of the traffic in Manhattan, stick mostly to protected bike lanes and travel at times of days when pedestrian and vehicle traffic are low.
