The Meteor Meter shows your relative position compared to others in your age group and gender for the specified distance.
A male runner in the 40-44 age category that can complete a 5k run with a 5:00 /km pace in a time of 25 minutes and 01 second can expect to complete a marathon run with a 5:30 /km pace, for a time of 3 hours 52 minutes and 31 seconds.
The equivalent time and pace is calculated based on the runner's relative fitness level as compared to other runners in his age group.
The reported result is an achievable goal time. To achieve this you may need extra training tailored to the distance. The greater the difference is between the reference distance and the goal distance, the more likely it is that you will need extra training.
