All right, so since enough people are interested in this, I've decided to go ahead and make this log thread. Post your miles here! Remember to include a) your means of exercise, b) how many miles you went, and c) the new DTF total.
For example:
Ran 5 miles. DTF total: 71 miles
Biked 6 miles. DTF total: 74 miles
It doesn't have to be that formal. Just be sure to include all the right information so the next poster can know what to build off. And if you want to log your miles at the end of the week/month/year, feel free to do that too.
Conversions are based on calories burned. (props to rumborak for the suggestion)
Exercises with a 1:1 mileage ratio:
Cardio machines (sans bike)
Running/Jogging
Hiking
XC Skiing
Exercises that need converting:
Biking - divide in half
Sports - 10 minutes is equivalent to a mile
Swimming - multiply by 4
Walking - divide in half
Ask for other conversions if you need them.
Start logging tomorrow! Good luck!
