Formula 1 Practice 1 begins at 08:30 UTC on Thursday, September 24 — 12:30 local time in Baku — and runs for one hour. Formula 1’s official Azerbaijan race hub confirms the session slot, then a second practice follows at 12:00 UTC. This is a preview of the opening session, not a report from it: GearPulse is not trackside and does not have live timing or telemetry.
Baku’s opening run matters because it joins two very different demands in one lap. The 6.003km, 20-turn street circuit compresses the car through its old-city section, then asks it to accelerate cleanly onto a long waterfront run. Formula 1 lists 51 laps and 306.049km for Saturday’s Grand Prix, but those race figures are context rather than a target for this one-hour practice. The useful question today is simpler: can a car be precise in the slow walls-lined corners without sacrificing its high-speed efficiency?
The first useful data is not a lap time
Practice 1 is where teams turn simulation assumptions into a baseline. Baku gives them a particularly sharp checklist: brake temperatures into the heavy stops, traction out of slower corners, ride control over a street surface and energy deployment over the long full-throttle sections. A headline lap early in the hour can be affected by tyre condition, traffic or a low-fuel run; repeatable behaviour across several laps is the more valuable evidence.
That makes the session relevant to GearPulse readers interested in how complex machines are tuned under constraints. The fastest-looking configuration is not necessarily the most useful one. Engineers are balancing cooling, braking confidence and aero efficiency against the cost of a car that feels nervous close to Baku’s walls.
Formula 1’s new active-aero era also changes how the straight should be described. F1’s current circuit guide explains that the front and rear wings now move to reduce drag, replacing the earlier DRS framework. Baku City Circuit’s technical notes still identify two traditional DRS-zone reference points: one after Turn 2 and another after Turn 20. For the opening practice, the practical issue is therefore not an old-style DRS passing count but whether the active-aero and energy settings deliver a stable, repeatable run to Turn 1.
Wind is the variable worth respecting
Motorsport.com’s Thursday forecast calls for mild, mostly sunny to partly cloudy conditions around 22–25C, with rain unlikely. It also flags Caspian Sea breezes as a potential complication between the buildings and through Baku’s narrower sections. That is a more useful warning than a generic “dry track” label: a gust can change the load on a car at turn-in, and the driver has little runoff with which to absorb a surprise.
The likely dry running should allow teams to compare setup changes without rain obscuring the picture. It does not make conditions static. Wind direction, tyre warm-up and surface evolution can all alter the compromise between a low-drag setting for the long run and enough stability for the old-city sequence.
Strategy begins as an experiment
There is no race strategy to execute in Practice 1, but there is a strategy programme. A sensible opening plan will usually include installation work, system checks, a representative aerodynamic run and longer stints that expose tyre and brake behaviour. At a temporary street track, protecting a clean run can be more productive than chasing a single perfect lap: interruptions and traffic make comparisons expensive.
Autosport’s Baku anniversary preview frames the circuit as a fast street course whose character may suit the newer generation of cars differently from the previous ground-effect era. That historical comparison is the right lens for today. Baku entered F1 as the 2016 European Grand Prix before becoming the Azerbaijan Grand Prix in 2017; a decade later, the layout’s contrast remains its essential test.
Team context without a scoreboard
The first session also begins with one clear personnel note: The Race and Motorsport.com report that Isack Hadjar is back in Red Bull’s race seat after recovering from a wrist injury, while Liam Lawson returns to Racing Bulls. That makes the opening familiarisation work particularly meaningful for Red Bull, but it is not a prediction of performance.
Across the grid, the same technical dilemma applies. A setup that buys speed on the waterfront may demand more from braking and rotation in the tight sections; a car tuned for confidence near the walls may give away some straight-line efficiency. Practice 1 will not settle that argument, but it will show which direction each team chooses to explore.
For viewers, the most revealing signs are modest ones: stable braking into Turn 1, clean traction without repeated corrections, and cars that can complete representative runs despite the wind. Baku is a circuit where confidence has to be engineered before it can be driven.
