Galloway suggests working a MM roughly each two weeks, to watch progress and have probably the most correct mile measurement on the finish of your season. When you’re not involved about actual particulars and simply desire a good estimation of your capabilities, inserting one into your coaching plan when curiosity strikes you is ok, too (simply plan it for a day that you’ve recent, well-recovered legs).

A observe is the only approach to measure your MM, though GPS information and a stretch of flat highway works nice as effectively). When you go for the highway, make certain to measure your distance a number of occasions earlier than you run your MM–accuracy counts on this calculation.

Heat up with 10 minutes of very simple working, adopted by just a few accelerations to get your legs prepared for a speedy mile run (a mile on a normal 400-metre observe is 4 laps across the inside lane).

Tempo your self as whilst attainable over every 400-metre stretch. When you’re in a position to, word how briskly you ran every quarter-mile, or have a look afterward at your information for future comparability. Watch out to not take off too onerous in the beginning–run about as onerous as you’ll be able to at a good tempo for one mile, with out pushing your self to the purpose of feeling such as you’re going to puke. On the finish of the mile, it’s best to really feel such as you wouldn’t have the ability to keep various hundred metres extra at that tempo.

You should use the magic mile calculator on Jeff Galloway’s web site to work out your coaching and race paces based mostly in your MM time. When you use min/km to coach, you’ll be able to regulate the tempo by dividing by 1.6.

The calculation makes use of the next method for tempo in miles (we’ve added kilometres, as effectively):

Add 33 seconds to your magic mile for 5K tempo (in miles)

Multiply your magic mile time by 1.15 for 10K tempo (per mile) or by 0.71 for min/km

Multiply your magic mile time by 1.175 for 16K (10 mile) tempo or by 0.73 for min/km

Multiply your magic mile time by 1.2 for half marathon tempo or by 0.75 for min/km

Multiply your magic mile time by 1.3 for marathon tempo or by 0.81 for min/km
