The Central Park bicycle climb starts in the east 70‘s at about the boathouse and continues all the way up to about 106th street where it levels off.
Then it banks hard left and nosedives into an “S” curve down around the Lasker Rink.
You can fly, picking up speed all the way down and around the long sweeping right at the bottom.
Then it gently graduates to the exit at 110th.
I’ve scared myself a couple times.
1972, number 14 on the Billboard Hot 100
Have a great weekend!
