How do you predict race times?

It’s based on a formula originally devised by Pete Riegel, a research engineer and marathoner, and has been widely used for over 20 years. The formula is T2 = T1 x (D2/D1) 1.06 where T1 is the given time, D1 is the given distance, D2 is the distance to predict a time for, and T2 is the calculated time for D2.

How can I predict my mile time?

Dr. John Robinson suggests a different approach. He says that you can add 20 seconds to your mile each time you double your distance. If you have done a half marathon, take your average minutes per mile, add 20 seconds and multiply by 26.2.

How accurate are Garmin predicted race times?

First-beat state their prediction is usually within 3.5 ml/kg/min, which is relatively accurate. A recent study looked at the accuracy of watch VO2 prediction vs. actual VO2 max in 28 random individuals. They found that for low fitness individuals, the watch prediction was mostly accurate.

How do I predict my marathon time?

Run one mile as fast as you can, middle-school style (don’t barf or die, though). Then to predict your marathon time, take your mile time (in seconds) and multiply by 1.3. The result is your marathon pace per mile, in seconds.

How fast could I run a 5K?

Average time and pace Everyday runners can aim to complete a mile in about 9 to 12 minutes. This means you’ll finish a 5K in about 28 to 37 minutes. Walkers can expect to complete a mile in about 15 to 20 minutes. Walking at a brisk pace should enable you to finish a 5K at around the hour mark.

Can VO2 max predict race times?

Put simply, the VO2 max metric on your watch is wrong and it means next to nothing. I’m sorry if you’ve been using this to direct your training, but it’s impossible to predict your VO2max and more importantly, your race times from your watch.

Is Garmin 5K predictor accurate?

They go on in further detail to describe a potential scenario in which the resulting value could vary as much as 9%. But they say that in most cases the margin of error falls within 5%.

Can Garmin predict race times?

Select Menu > My Stats > Race Predictor. Your projected race times appear for 5K, 10K, half marathon, and marathon distances.

Is Garmin VO2 accurate?

Taken as a whole, the studies suggest that the Garmin methodology can give you a VO2 max estimate within about 5 percent of your true value.
