F1 race live: gaps, pit stops, tyres and flags
How to follow an F1 race live with free data: gaps, intervals, pit-stop strategy, tyre state and flags by sector.
Summary
- The gap to the car ahead tells you whether an overtake or an undercut is near; the gap to the leader, how the race is going.
- Tyre (compound, laps and new or used) and the pit-stop count let you read each driver's strategy without watching the TV.
- The flag bar by sectors and the race-control messages warn of yellows, safety car and red flag.
Step by step
Gap to the leader and to the car ahead
Two different columns: the gap to the leader adds up the whole race; the one to the car ahead is what decides attacks and defences. Under a second is usually overtaking range.
Read the strategy in the tyres
A driver on old tyres whose pace is dropping is close to pitting; another on a fresh set with better sectors may be doing an undercut. The stop counter completes the picture.
The pace chart
Lap pace uses only valid laps (no pit laps, flags, safety car or installation lap) and colours each dot by tyre. It shows who is losing pace and when.
Flags and neutralisations
Under a safety car or VSC, pitting costs far less time: the flag bar and race-control messages tell you what happened and where.
Track conditions
Air and track temperature, humidity, wind and rain help explain why a tyre degrades sooner or why the pace changes.
When the race ends
The official data arrives afterwards: race analysis, overtakes, strategy and telemetry, and you can relive it with the replay.

Glossary
- Undercut
- Pitting before the car ahead so that, on fresh tyres, you lap faster and come out ahead when they stop.
- Stint
- The part of a race a driver runs on the same set of tyres, between two pit stops.
- Compound
- The type of tyre (soft, medium, hard…): softs grip more but wear out sooner.
- Safety car
- A car that comes out on track after an incident so the cars lap slowly and bunched while the track is cleared.
- Virtual safety car (VSC)
- A neutralisation in which all cars must stay below a set time, without the safety car coming out on track.
- Yellow flag
- Danger on track: slow down and do not overtake in that zone.
