# The Magic Mile

The Magic Mile is a one mile prediction calculator designed by Jeff Galloway to predict your race time.

The Magic Mile will determine:

If your race goal is realistic

How much improvement can be expected

In other words, the Magic Mile removes the guesswork out of goal setting.

The formulas for a full and half marathon are as follows:

Full marathon - One mile time X 1.3

Half marathon - One mile time X 1.2

So, for example, if you run an 8 minute magic mile, your marathon pace per mile would be 10:24 (8 X 1.3).

To run, the mile, first do a good warmup. Then, run 1 mile so that, when you finish, you are breathing hard (not gasping) and you do not think you can go another half mile (about 80% - 90% of your maximum sprint speed).
