2. Average Half-Marathon Time for Intermediates 

For some experienced runners who have participated in half-marathon races a number of times already, their goal might be finishing off the marathon race in a faster time. While many aim to target completing in 2 hours, the average half marathon time for intermediate runners is between 1:45-2:10 hours.

ESTIMATING YOUR FINISH TIME 

ESTIMATING YOUR FINISH TIME

It is vital to estimate your finishing time for the half-marathon race beforehand as this really helps you to pace yourself properly. The estimation also sets as a measurable target and expectation for you to plan your training accordingly.

However, it is well-known that predicting the finishing time for a long event like the half-marathon is not an easy feat. There are various unpredictable factors that can actually influence your performance during the race such as race condition and environment, physical or psychological health of competitors, weather conditions, your health situation on the racing day and so on.

Despite that, there are various easy formulas and calculations developed and used by many runners for their reference and setting as a benchmark for themselves. Some researchers suggest the following equations to estimate your own race time with the utilization of body fat index:

For men, half-marathon race time (min) can be predicted by this equation:       {142.7 + 1.158 × body fat percentage} – {5.223 × running speed during training session (km/h)}.

For women, half-marathon race time (min) can be predicted by this equation:   {168.7 + 1.077 × body fat percentage} – {7.556 × running speed during training session (km/h)}.

Aside from the easy formulas mentioned above, runners also make good use of the race time prediction calculators or charts that provide the finishing time data of participants from recent races to estimate their finishing time. Having known your estimated finishing time, you may further use a half-marathon pace calculator to determine the average half-marathon pace needed.
