I will be challenging myself, for every £1 raised up to £400 I will run a mile for this during the month of December. This roughly breaks down to 100 miles a week or a half marathon every day for a month.

If every mile is ran at a 7:30 minute pase this would work out to be 50 hours of time that will be spent running.

I will be logging all miles via Garmin Connect/Strava which will show my pace and elevation change for each exercise and is the best way I have found to log the mileage accurately.
