TL;DR
- Use Strava for the social network and segments, Garmin Connect for the free analysis that ships with your watch, and intervals.icu for the deepest free training analytics that work with any brand.
- Strava is the only one that paywalls core analysis: the subscription is listed at €10.99/mo or €74.99/yr, and Fitness & Freshness, Performance Predictions, and filtered leaderboards sit behind it.[1][2]
- Garmin Connect keeps all pre-existing features free; Connect+ ($6.99/mo or $69.99/yr) is an optional add-on, not a paywall.[3]
- Intervals.icu has a fully free core platform with an optional $4/mo Supporter tier and syncs with Garmin, Strava, Wahoo, COROS, Polar, Suunto, and Zwift.[4]
These three are not really competitors; they are layers. Most athletes upload from a Garmin (or COROS, Wahoo, Polar) into Garmin Connect, mirror to Strava for the social feed, and pull into intervals.icu for analysis. The real question is which one you pay for. This comparison uses each vendor's published pricing and feature pages, with no in-house testing claim. All figures were verified as of 2026-05-25.
Verified price and role comparison
| Spec | Strava | Garmin Connect | Intervals.icu |
|---|---|---|---|
| Price | €10.99/mo or €74.99/yr[1] | Free; Connect+ $6.99/mo[3] | Free; Supporter $4/mo[4] |
| Core analysis free? | No (paywalled)[2] | Yes[3] | Yes[4] |
| Social / segments | Yes, its main strength | Limited social feed | No social layer |
| Cross-brand sync | Yes | Garmin-first | Garmin, Strava, Wahoo, COROS, Polar, Suunto, Zwift[4] |
| Best at | Community, kudos, segments | Free watch analysis | Fitness/fatigue/form, power analysis[4] |
Strava sells the network, then charges for the analysis
Strava's free tier still gives you unlimited GPS uploads, kudos, comments, clubs, and segment views, which is most of what makes Strava feel like Strava.[2] What moved behind the subscription is the training analysis: Fitness & Freshness, Performance Predictions, filtered leaderboards, and offline maps all require the paid tier, listed at €10.99/mo or €74.99/yr.[1][2] So Strava is the one of the three where the analytical features cost money, while the social glue stays free.
Garmin Connect keeps the analysis free
When Garmin launched the Connect+ subscription, it explicitly kept every pre-existing feature and your historical data free.[3] Connect+ at $6.99/mo or $69.99/yr adds AI-generated insights and an expanded dashboard on top, but Body Battery, Training Status, HRV trends, and the activity analysis you already had remain free on a compatible device. The catch is that Garmin Connect is Garmin-first; it is the best free analysis layer if you own a Garmin, less so if you ride a COROS or Wahoo.
Intervals.icu is the free power user's tool
Intervals.icu gives away the deepest analysis of the three: fitness, fatigue and form (CTL/ATL/TSB-style modelling), interval detection, power-curve and HR analytics, a workout builder, and a training calendar, all on a free core platform with no trial limit.[4] The optional Supporter tier is $4/mo and adds weather analysis, the annual plan builder, full Strava history import, and custom zones.[4] Crucially it is brand-agnostic, syncing with Garmin, Strava, Wahoo, COROS, Polar, Suunto, and Zwift, so it sits on top of whatever device you own.[4]
Decision frame
- You want the social feed, segments, and community: Strava, free tier is enough for most.
- You own a Garmin and want free analysis with no extra app: Garmin Connect.
- You want the deepest free training analytics, any brand: intervals.icu.
- You are a data-driven cyclist or triathlete: upload to intervals.icu and keep Strava free for the social layer.
The verdict: keep Strava on its free tier for the social feed and segments, lean on Garmin Connect for free analysis if you own a Garmin, and run intervals.icu for the deepest training analytics on any brand. Since these are layers rather than rivals, the only real decision is what you pay for, and intervals.icu gives the data-driven athlete the most free depth, so Strava is the one to leave unpaid.

Yes. The core platform is free with no trial limit, and the optional Supporter tier is $4/mo. It syncs with Garmin, Strava, Wahoo, COROS, Polar, Suunto, and Zwift.[4]
Which should a data-driven cyclist pick?
Intervals.icu for the analysis, since its fitness/fatigue/form modelling and power-curve tools are free and brand-agnostic. Keep Strava free for the social feed, and use Garmin Connect if you own a Garmin device.[4]
