Running a good half marathon time is something every runner has on their 'To-Do' list. Whether it’s a trail race or a road race, a 13.1 mile half marathon is the natural next step up from 10k, and one of the classic benchmarks to test yourself against. It's long enough to be a true test of fitness, stamina, pacing, form, and mental strength but short enough to be within reach of anyone willing to train consistently for a couple of months.
Our US Half Marathon calendar contains everything from small, community half marathons organized half marathons to some of the biggest races on the planet the Brooklyn Half - which attracts over 25,000 runners and is part of the Five Boroughs series.

How long is a half marathon?
How long is a half marathon?
Half marathon races are 13.1 miles or 21 kilometers, exactly half the distance of a full 26.2 miles or 42.2 km Marathon race. The average finishing time for a half in the US is around 1:55 with more seasoned runners often pushing for 1 hour 30 minutes or less. This makes half marathons the perfect choice for runners looking to step up to a new challenge from 10k races and an important milestone for those on their way to running a full marathon.
How long does it take to train for a half marathon?
How long does it take to train for a half marathon?
Half marathons count as the shortest ‘long-distance’ run, so training thoroughly is certainly advised before you arrive on race day. It usually takes around 8 weeks to prepare for a half marathon if you are used to running shorter distances. It is really important to build slowly to avoid injury and we’d recommend finding an easy-to-follow training plan to keep you on track.
Do I need to run every day to train for a half marathon?
Do I need to run every day to train for a half marathon?
Getting some miles under your belt is important before you take part in a half marathon race, but overtraining is a common mistake made by less experienced runners looking to make the step up from 5K runs. Slowly building your fitness and endurance with rest days to recover is the best way to ensure success when you hit the starting line.
