Live tracking that shows each participant's split times at checkpoints

Are you looking for a platform to use, or a short description/name for this feature?

If you mean a platform, RaceGoLive appears to match: it provides live participant tracking and shows split times at each checkpoint. RaceID also supports checkpoint splits and live results. (racegolive.com)

If you want live split times for each participant, the right tool depends on the event. Most of these depend on the race's own timing system, so you usually need the race to use it.

Event-specific trackers (for following a race you're watching)

• UTMB Live shows live rankings, split times at each checkpoint, and webcams. Tracking relies on checkpoints and the chip worn by each runner, not continuous GPS, so positions can lag between checkpoints.
• Hyrox Live Race Tracker lets you search by name or bib and shares splits from the official results portal. Splits are pulled every 30 seconds, and splits appear within a few seconds of an athlete crossing each timing mat.
• Columbus Marathon's RTRT and the Marine Corps Marathon tracker show per-checkpoint times for their races. For Columbus, the information will be based on five checkpoints along the course.

Apps that work across many races

• Racetimer Live Results (Android) lets you see their split times and finish time as they are recorded, plus optional checkpoint notifications. It needs no account.
• SportSplits (iOS and Android) covers races mainly in Australia, New Zealand, and Asia-Pacific, with official times the moment athletes cross each timing mat, with splits, pace and rankings.
• LivePlanit (Competitive Timing) shows projected finish times that update at every split for races it times.

If you're organizing or timing a race yourself

• RACE RESULT software offers live timing data from all points – start, split, and finish, and can be used on a phone.
• RaceClocker is a cloud-based option where timekeepers in the field can use any smartphone, tablet or laptop either online or offline.
• RaceSplitter is an iPhone/iPad app for coaches and small events that provides accurate split times, lap times and standings during the race.
• PrimeTime Timing offers real-time athlete tracking using antennas and bib transponders, for larger events.

Tips

• Check the race's official site first. Their approved tracker is usually the most reliable source.
• Positions between checkpoints are often estimates, not live GPS, so use split times for pace and treat location as approximate.

Live tracking that displays participant split times at checkpoints is achieved through a combination of hardware (timing systems) and software (tracking/results platforms).

Whether you are an event organizer looking to implement this or a participant/spectator trying to follow a race, the systems generally fall into these categories:

1. How It Works (For Organizers)

• Chip Timing (RFID): This is the industry standard for marathons, cycling, and multi-sport events. Participants wear a small chip (often embedded in the bib or on an ankle strap). When they cross "timing mats" (antennas) placed at the start, finish, and intermediate checkpoints, their unique ID and timestamp are recorded instantly.
• GPS Tracking: For trail races, ultra-marathons, or events where physical mats are impractical, participants carry GPS trackers. These devices ping their location to a server, and the tracking software automatically records a time when the participant enters a "virtual" or "geofenced" checkpoint.
• Manual/Scanner Timing: For smaller events, organizers may use apps or handheld scanners to log participants' bib numbers as they pass checkpoints.

2. Popular Platforms

Race organizers typically use specialized software that integrates timing data with a live, public-facing leaderboard or map. Popular solutions include:

• MYLAPS: One of the most widely used systems for professional race timing, offering comprehensive live tracking, leaderboards, and app integration.
• RaceDay Real-Time Suite (RunSignup): A robust platform often used by timers that includes features like "RaceJoy" for live GPS tracking and integration with various chip systems.
• Webscorer: Provides both GPS-based timing and tracking, allowing organizers to set up virtual checkpoints that participants' phones detect automatically.
• Open Tracking / Racemap: These platforms specialize in live GPS tracking for events, offering interactive maps where pins move in real-time and split times are automatically updated as participants pass predefined points.
• Race Roster: Offers predictive tracking features that estimate a participant's location and finish time based on their split data and pace.

3. What to Look For

If you are looking to provide or follow live split times, keep these factors in mind:

• Reliability: Professional systems usually include backup procedures (e.g., manual logging or camera verification) to ensure no splits are missed if a chip fails to read.
• Transparency: Good platforms clearly distinguish between "recorded" split times (official, at a checkpoint) and "estimated" positions (calculated based on pace between checkpoints).
• Integration: The best experience comes when the tracking system is integrated with the race's official app, allowing spectators to receive push notifications for their favorite athletes.

If you are a participant or spectator: You can typically find these features on the race's official website or by downloading the event-specific app, which usually links directly to the timing provider's results page (e.g., RTRT.me, the race's own portal, or the timing company's leaderboard).

If you’re looking for a name for this feature, live race tracking with checkpoint split times fits. It lets viewers follow participants and see their recorded times at each checkpoint. ¹²

For example, Geo Tracks describes a live leaderboard with both split times between checkpoints and cumulative times; Columbus Marathon’s tracker shows participant times as they cross each split point. ¹²
