Ronhill Infinity Marathon Twin Short

The running short appears to be a fairly simple garment, but there is much more to these diminutive trousers than meets the eye.

Designed to provide you with the maximum freedom to move, running shorts come with a variety of styles to suit distinct types of runners and running.

So, whether you gobble up track, ravage local roads, or thump through the toughest trails, there’s a short suited perfectly to your needs.

There are many elements differentiating the various styles of shorts. These include length, whether they have lining or a compression layer underneath, what materials are used, and the type of fit.

Your running and training type will dictate the style of short best suited to your needs, giving you the best chance to perform at your best.

What length of running shorts should I go for?

While there are no hard and fast rules, different short lengths lend themselves to different purposes. Have a look at some of the scenarios befitting the scale of short lengths. 

Short length (three inch)

Shorts that finish high up the thigh provide the best ventilation and range of movement when you run, which is why they are favoured by competitive runners in general. They’re ideal for both sprinting and long distance road running (such as a marathon) as their technical construction, lightweight and non-restrictive cut make them the ideal choice for all-out performance.

Medium length (five inch)

Providing a balance between the aggressive competitiveness of the short short and the robustness of the long, medium length shorts give you the best of both worlds. The most popular style among runners, the medium short is a versatile garment for the modern runner and ideal for those who vary their training from track to trail.

Long length (seven inch)

For shorter running distances a longer short is often preferred. These shorts are also perfect for changeable conditions, as well as running off-road, offering you protection against debris or shrubs. It’s important, however, to ensure the material used will not retain heat or moisture and disrupt your comfort. Look for sweat-wicking fabrics and ventilation to ensure they don’t hamper your performance. This style of short is also more likely to have pockets for quick and easy storage. 

Running shorts explainer

While the various lengths provide a basic idea of the type of shorts you need for your running discipline, there are a number of other features to look out for. There can be, however, some confusion about the purpose of these features, so here’s a look at some of the frequent questions asked…

Where are running shorts measured from?

The measurement used for running shorts is the inner seam - that is, the distance between the bottom of the short’s leg and the seam at the base of the crotch. For those of around average height, a three inch short will finish on your upper thigh, a 5" short should approach the mid-thigh area, and a 7" short will finish just above the knee. 

What are split running shorts?

Split running shorts take the advantages of short-length shorts a step further, and are the garment of choice for serious runners taking part in a competitive race or seeking to break a PB. They provide super-lightweight comfort and complete freedom of movement.

Why do running shorts have lining in the inside?

If you’re new to running, it may surprise you to learn you’re not supposed to wear underwear under your running shorts. An inner lining is instead provided to keep you secure and comfortable, and wearing another layer of underwear underneath can cause chafing and discomfort. The shorts and the lining are designed to keep you ventilated and fresh over long distances, where the build-up of sweat and constant motion could cause a nasty rub. An increasingly common alternative to using a lining inside the shorts is to incorporate compression materials under the shorts.

Why do runners wear compression shorts?

As mentioned above, compression shorts can be incorporated into traditional shorts to act as a replacement for the inner lining. These are known as 2-in-1 shorts. Compression can contribute to better blood flow, muscle activation, and general comfort.

Do compression shorts help prevent chafing?

With less moving parts, as it were, compression wear can greatly reduce chaffing. With rubbing fabrics eliminated, you can run further and in more comfort than ever before. Be sure not to wear underwear under compression fabrics or these benefits can be quickly undone.

 

Shorts type for trail, track, or road

Here's some examples of various shorts at differing lengths and for different disciplines to help you find the right style for you. Of course, the shorts below are categorised only to illustrate their likely use, so choose whatever type of short makes you most comfortable no matter your preferred terrain or running style. 

Shorts for the trail runner

Trail and urban runners tend to wear tougher gear and can afford to wear slightly heavier kit. 2-in-1 shorts provide extra protection from the elements and comfortable support even on the longest of routes.

Combining a moderately compressive liner with a looser outer-layer, these 2-in-1 shorts from Salomon perform just as well on the road as the trail. The inner is made with a 4-way stretch fabric to provide increased mobility, while a zipped pocked and stretch waist offer added convenience.
