Spinning vs running
A 45 minute spinning class burns about 470 kcal, a 5 km run about 350. The spin class wins by 120 kcal.
The difference
120 kcal burned
A spin class is mostly hard work for its whole length, with an instructor pushing you through intervals. A 5 km run like a parkrun takes most people less time than a class, so it is a shorter workout.
Time for time they are close: 30 minutes of easy running is about 330 kcal, and a 10 km run about 700, more than the 625 for an hour of spinning. These numbers are for about 70 kg.
Spinning is easy on the knees, running needs no booking. In Caltype just type "spin class 45 min".
