In addition to distance, marathons & ultra-marathons -running and swimming- are also defined by how long it will (roughly) take one to complete. On a side note, we recommend that you check out our post Can You Do Too Much Swimming? How Much is Too Much?! (Age & Experience) How Long Does A Marathon & Ultra Marathon Take to Complete? Though this is the widely accepted definition there is some debate over whether the minimum distance should be anywhere from 15K to 25K. Much like with running marathons vs ultra-marathons, in swimming, an ultra-marathon is typically any swimming event over 6.2 miles (10K). And, yet, others define marathon swimming as open water swimming longer than 10K. Additionally, other literature shows some regions define marathon swimming as any open water swim that is over 1500 meters. While today 6.2 miles (10K) is the widely accepted distance for marathon swimming, the early days of marathon swimming, circa the 1960s, saw marathon swim distances of at least 10 miles (16K) due to the relative times involved in completing it. While FINA (as well as many other swimming organizations) defines marathon swimming as 6.2 miles (10K), a few swimming organizations, such as the US Masters Swimming and USA Swimming, have no definitions for marathon swimming. The above is FINA’s definition of marathon swimming which states that a marathon swim is 6.2 miles (10K) in length the Olympic 10K Marathon Swim being its most widely known race. However, the common minimum distance of a marathon swim is defined as 10K (6.21 miles) which is the distance used in the Olympic marathon swimming event and accepted by many swimming organizations. To make a marathon in under 4 hours, you need an average pace of 5.69 min per km (5 minutes and 41 seconds).While running marathons have specified distances, marathon swim distances will vary. The next value, your required pace, is what probably interests you the most. Our marathon time calculator will automatically display the speed you need to achieve such a result – 10.55 km/h.

For example, you might want to run a full marathon in under four hours, so you set your goal to 4h. Feel free to change the units to miles if you prefer the imperial system.ĭecide on your goal. In the case of a marathon, it is 42.195 km. The marathon pace calculator will automatically fill in the field "distance," showing you the distance you'll have to run. Let's assume that you plan to do a full marathon.

It can be a marathon, half marathon, or even a 10-kilometer race. To find it out, simply follow the steps below:Ĭhoose the type of race you will participate in.

The first application of this marathon calculator is planning your race in advance – that is, establishing what pace you require to finish in a given time.
