was the super high cal burn 3 mile one. this took me 60 min to do and and i would say it was at least at 5mph. was really a great work out. so i went to list my activities on fit day and it says that i only burned 231 cals at 4.5 they did not have a choice for 5mph then i went and checked on 3fc and it says 498 at 4.5 mph. why the difference in the 2. but was a good work out i almost felt my but get smaller...lol
