Best treadmill and indoor running classes in London

London's treadmill and indoor running scene has built its own identity distinct from the US formats it's drawn from. 1Rebel's Reshape class introduced the tread-and-floor format to the city on its own terms, Rumble Gym has developed a cult following around its dedicated tread sessions, and Victus Soul has emerged as a home-grown competitor to Barry's with its own HIIT and Run format. This ranking is built from 237,679 verified ClassPass member reviews collected between January 2025 and February 2026, covering studios across the city from Dalston to Chelsea to Oxford Circus.

Rankings weight each studio's average member rating on treadmill and running-specific reviews, adjusted by review volume and consistency. The studios below represent the best treadmill experiences available on ClassPass in London right now, based on what members who've done the classes actually said about them.

Eight studios across London, from the City to North London, ranked by members who take their tread sessions seriously.

  1. 1

    RUMBLE, Dalston, London

    • 4.8
    • 25,562 reviews

    Rumble Gym in Dalston has developed something rare in London's boutique fitness scene: a treadmill class with its own dedicated following. The Tuesday tread session in particular has achieved the kind of word-of-mouth that fills classes without marketing, with members describing it in terms usually reserved for events rather than classes. The studio's zero-carbon ethos extends to its equipment and operations, giving the space an identity that goes beyond the workout itself.

    The instruction quality on the tread classes is the consistent thread through the reviews. Rumble's coaching approach calibrates to individual ability within the group format, which means the class works for people at different running levels without the instructor having to run two separate sessions. For Hackney residents and anyone willing to make the trip east, this is one of the few places in London where the treadmill class is the actual draw.

    "Tuesday tread is my one non-negotiable. Get yourself to this class. The reviews are true."
    "First time I came to this class and I loved it. It's so challenging but equally tailored to your individual abilities. Highly recommend [Instructor]'s tread. The vibe was amazing!"
    "The best class at Rumble. Hands down. Don't know what I'd do without [Instructor]'s treads."
  2. 2

    Victus Soul, Waterloo, London

    • 4.5
    • 5,347 reviews

    Victus Soul Waterloo is the newer of the two London locations, and it brings the HIIT and Run format to a part of the city that's underserved by treadmill-focused studios. The class alternates between treadmill intervals and strength work on the floor, with programming described by members as better sequenced than the comparable Barry's format. The light setup is worth a mention: the white strobe during sprint intervals is intense, which is useful information if you're sensitive to flashing lights.

    The instruction here is clear and paced well, with coaches providing explicit treadmill speed guidance throughout rather than leaving members to figure it out mid-class. For South Bank residents or anyone coming out of Waterloo station, this is the most convenient serious treadmill class in the area, and the reviews suggest it delivers on quality, not just location.

    "I tried one of the lunchtime classes that combined strength training with treadmill work. It was a solid mix that kept things interesting. The [Instructor] was friendly and gave clear updates throughout the session, which really helped with pacing and form. Would definitely go back!"
    "It was a great class and so much fun! The only thing I'd say is the white strobe light feels a bit too intense when running fast on the treadmills. The red lights are absolutely fine but found this a bit much. Nice staff and studio."
    "Better than VS Aldgate or Barry's."
  3. 3

    1Rebel, Chelsea, London

    • 4.0
    • 10,701 reviews

    1Rebel Chelsea is one of the newer additions to the 1Rebel network, and it pairs the Reshape treadmill-and-floor format with a Reset recovery concept that includes sauna and cold plunge. The class itself alternates between Woodway treadmill intervals and a dumbbell-loaded floor section timed to the music, and the Chelsea location draws a crowd that takes the format seriously. The reviews show this location's instruction as clear and beginner-accessible, which is consistent with 1Rebel's approach across other sites.

    The addition of the Reset recovery option post-class is genuinely uncommon in London's boutique fitness market. For people who want to combine a hard treadmill session with structured recovery in the same visit, the Chelsea location is the only 1Rebel that currently offers it. The Reshape class is worth booking on its own merits regardless.

    "Great class. [Instructor] explained everything really well and I felt like I had a really good workout."
    "Dare I say a better workout than Barry's. Loved it."
    "The music was far too low and it completely killed the Reshape vibe. Without the loud energy, it felt like a dull treadmill workout. The [Instructor] was okay. Please reconsider the music level."
  4. 4

    1Rebel, Southbank, London

    • 4.0
    • 28,489 reviews

    1Rebel Southbank is one of the highest-volume 1Rebel locations, and its Reshape class has been the go-to treadmill workout for people working or living along the South Bank for years. The Woodway treadmill setup and the 1R floor platform are calibrated for the format, and the instruction quality has a consistency here that benefits from the sheer volume of classes run through this location.

    New members get particularly strong onboarding: the Southbank team is consistently cited for walking first-timers through the treadmill controls and class flow before the session starts, which removes the anxiety of figuring out the format mid-class. The tread and floor rounds are clearly delineated, and the endurance-focused programming on this site gets specific mentions from members who come for running improvement rather than general fitness.

    "Amazing. [Instructor] was super encouraging and supportive , a great way to start the day. I'd never done a HIIT class or even touched a treadmill but was able to keep up."
    "Such a good workout. Mix of treadmill and weight work. [Instructor] was really friendly and helpful with the induction, great vibes all round!"
    "Such a good coach. Really loved the tread and floor rounds with a focus on endurance."
  5. 5

    Victus Soul, Aldgate, London

    • 4.1
    • 29,585 reviews

    Victus Soul Aldgate is the original City of London location for the HIIT and Run format, and it serves one of the densest working populations in London. The format alternates between treadmill intervals and either floor HIIT or boxing depending on the class, and the progression from warm-up intensity to max-output sprints is what members who've done multiple sessions call out as the defining feature of the Victus programming approach.

    The instruction energy here is consistently high, and the class community in the City location reflects the area: people fitting an intensive session into a busy schedule, focused on efficiency. The tread-to-floor balance is well-paced, with coaches providing clear cues for both sides of the room simultaneously, and the overall flow of the class is smoother than the equivalent format at some competing studios.

    "[Instructor] is the best teacher for this type of class. So much fun, such a vibe. Thanks for pushing us to our max."
    "Loved [Instructor]'s energy! Paced the class well between tread and floor. Amazing class and will be back!"
    "Great flow between treadmill and floor throughout the session. Enjoyed the gradual increase and build-up to max intensity. Highly recommend."
  6. 6

    1Rebel, Holborn, London

    • 4.3
    • 36,320 reviews

    1Rebel Holborn is the West End outpost of the Reshape format, located centrally enough to pull from multiple neighbourhoods without being tied to one. The Reshape class here allows members to self-select treadmill speed, which is a format detail that some find liberating after more prescriptive tread sessions. Members have occasionally requested the ability to double up on treadmill spots for extra cardio, and the Holborn team accommodates this when class size allows.

    The treadmill quality at this location uses Woodway machines, and the overall aesthetic of the space aligns with 1Rebel's boutique standard: well-appointed changing facilities, strong sound, and a class environment that feels deliberately designed rather than functional-by-default. For people in the Holborn, Covent Garden, or King's Cross area looking for a treadmill class that's easy to slot around a workday, this is the closest quality option.

    "Really enjoyed this. I like that we were able to control the speed of the treadmill."
    "Love when they let me do double treadmill. Thanks, 1Rebel team!"
    "Such a nice place and great classes. More welcoming, relaxed vibe than Barry's but still work super hard in the class."
  7. 7

    1Rebel, Oxford Circus, London

    • 3.6
    • 60,435 reviews

    1Rebel Oxford Circus is the highest-volume 1Rebel location, and that scale shows in everything from the size of the class to the range of instructors on rotation. The sheer volume of reviews at this location gives it a depth of coverage that smaller sites can't match, and members are specific in their feedback: the best sessions here are described as genuinely excellent, while more inconsistent sessions reflect the variation you'd expect from a large instructor roster.

    The Oxford Circus location's Reshape format runs the same Woodway treadmill and floor dumbbell structure as other 1Rebel sites, but the central location and larger class capacity can make it feel busier. Members who know their preferred spot in the room book early. For newcomers to 1Rebel who want the most accessible location in terms of transport, Oxford Circus is the natural starting point.

    "So much better than Barry's. Music isn't so loud that you can't hear the instructions and [Instructor] was excellent in guiding everyone, providing treadmill speed options. I thought I hated treadmill and floor box classes because they were confusing, but this class showed me it's really about the instructor and studio. Keen to come again!"
    "The best 1Rebel class I've been to yet! I loved how we were changing things up every 30 seconds on the tread. It made the class go quicker and way more fun! [Instructor] also timed the pushes on the beat of the music, which was so motivating."
    "Favorite workout class I've ever done! [Instructor] was fabulous and loved the music! I've tried many workout classes and this was amazing."
  8. 8

    1Rebel, Broadgate, London

    • 3.2
    • 41,443 reviews

    1Rebel Broadgate sits in the heart of the City financial district, and its Reshape classes draw the commuter crowd that wants an intensive treadmill session before or after work. The instruction style at this location gets strong marks from members who are new to the tread-and-floor format: [Instructor]-led sessions are described as particularly well-calibrated for mixing experienced runners with people who haven't been on a treadmill since secondary school.

    The location also has a practical advantage for cyclists: bike storage is available inside, just before reception. For members in the Shoreditch and City area, this is a genuinely convenient option for a structured treadmill class that doesn't require crossing the river. The sprint interval programming here is one of the few places in London where members specifically call out the tread intervals as useful for actual running improvement.

    "One of the best treadmill classes I've ever taken. [Instructor] is such a breath of fresh air. Often find Barry's and 1Rebel instructors a bit OTT and shouty but [Instructor] gets the mix of encouragement and instruction just perfect. Will definitely be coming back."
    "Really enjoyed this class. The format is great and as a runner it was perfect for strength and conditioning alongside interval work on the treadmill. Changing rooms are really nice and spacious. Bike storage inside, which was great for peace of mind."
    "The perfect blend of sprint interval protocol and strength training. [Instructor] was a really good coach and hilariously funny at times."
