This article explains RaceSplitter's support for categories in the timing of events.

Track one category in the app

The RaceSplitter app supports a single field called “Group” that can be used to segment participants and filter on results. For example, you could use this field to filter on “categories” such as:

  • Men
  • Women
  • Kids


Track two categories at the website

The website supports two user-defined fields called “Group” and “Team” that can be used to track any two arbitrary dimensions of a race. (And further down in this article, we’ll explain how these two fields can be used to track any number of categories!)

Although Team data isn’t sent from the website to the app (since the app can only filter on Group), the data is preserved in the original race at, and can be used for sorting and filtering on results published from the race.


Renaming the Group and Team labels

Group and Team fields can be renamed at the website.

Rename the Group and Team user-definable fields

For example, many organizers who time multiple races in parallel will rename these to “Category” and “Race”.


How to track any number of categories

Using the results filtering capabilities of the website, any number of dimensions can be tracked.

Let’s look at this by example. In the 2015 Sierra Blanca trail race, the organizer wanted to track:

  • Gender: Male & Female
  • Category: Absolute, Master, Veterans & Promesa (Kids)
  • Race: 29km and 42km

To track these three dimensions using only two available fields, they combined the first two in the definition of the “Group” field (which they renamed to “Categoria”). Here’s how they defined their “Groups”

  • Absoluto-F → Absolute category, female gender
  • Absoluto-M
  • Master-F
  • Master-M
  • Veterano-F
  • Veterano-M
  • Promesa

And here’s how they defined the values for the “Team” field (which they renamed to “Carrera”, which means “Race”):

  • Carrera 29km
  • Carrera 42km

Once results from this race were published to, the online filtering capabilities were used to browse and print the results of all the different categories and races. For example, in this video you can see how they filtered on “overall” females—i.e. all females across all categories—in the 29km race:

Planning your event

As you plan the timing of your first event, here's what you'll want to think about.

Start types

RaceSplitter supports four race start types — mass, interval, wave and variable.


While the RaceSplitter app supports a single user-defined field, complex categorization is supported at the RaceSplitter website.



This article explains how to publish, export and edit your results, both in the app and online.

Multiple Devices

Easily time intermediate points on the course, with RaceSplitter's multi-device support.

Auto-split Mode

Auto-split mode is useful for timing multi-lap races, but should be disabled for most others.

Bibless timing

This article explains how to create timing entries in rapid-fire mode without entering bib numbers.

The Timing Bar

The RaceSplitter "timing bar" allows you to assign the same time to multiple racers — useful when timing groups of people arriving together.

Racer Compensation

RaceSplitter supports the application of compensation factors in adaptive and handicap sports.

Automatic start time adjustment

Under certain circumstances, RaceSplitter will automatically adjust the race start time. This is both a benefit, and a risk.
