Six scenes from a training log that respects you.

A walkthrough of how Neverchill actually works - from the moment you drop a FIT file to the moment you export your archive. No carousel, no demo video, no sales tour. Just the product.

00Upload

Drop a ride, a run, a watch export, or a full archive.

Neverchill speaks FIT, GPX, and TCX natively. Drag a file or a whole archive into the uploader - we parse, dedupe, and queue every activity for analysis in seconds. Bring everything you have, even if you have been an athlete for a decade.

  • FIT, GPX, and TCX parsed natively - no third-party dependency
  • Attach media and photos to any activity (captions optional)
  • Per-activity audience picker - public, followers, close friends, coach, or private
  • Bulk import a full archive in one drop

01Analyze

Power, heart rate, pace, splits, climbs.

Every upload is recomputed against your real baselines. No category guesses, no recycled charts from 2014. The numbers reflect the athlete you are today.

  • 1-second power curve and best-effort intervals
  • Coggan zones from your latest FTP baseline, not a category default
  • Automatic lap detection, with manual splits when you need them
  • Climb categorization (Cat 4 to HC) with grade and VAM breakdown

02Plan

Workouts as first-class objects.

Plans, intervals, and prescriptions are real entities - not PDFs your coach emails you. Build structured workouts, link the plan to the actual ride, and talk it through with Domestique if you want a second opinion.

  • Structured intervals with target power, HR, or pace
  • Auto-link planned workouts to the activity that completed them
  • Domestique chat with full context: your baselines, your recent load, your goals
  • Drag-and-drop calendar with weekly templates

Coach
Aim for 95-102% FTP per interval. Your last threshold block was 12 days ago - start conservative on interval 1 and build.
03Train load

CTL, ATL, TSB rendered correctly.

Training load only works if the inputs are right. We compute TSS against the FTP you actually have, on the date you actually had it - not a single static number you set on day one.

  • CTL, ATL, and TSB charted against your real FTP history
  • Baseline timeline - FTP, LTHR, max HR, weight, all versioned
  • Updates instantly when you upload, not on a nightly cron
  • Honest about what is measured vs. estimated

04Share

A feed for athletes, not advertisers.

A social layer that exists because training with other people is good, not because someone needs to sell ad slots. No segments-as-product, no notifications engineered to drag you back.

  • Follow approval if you want it - public, private, or per-request
  • Reactions and comments where they matter (kudos that mean something)
  • No segments leaderboard hawked back to you as a paid upgrade
  • No ads, ever - that is not the business

"First proper threshold work since the knee thing. Felt smooth, held 96% for both."

No segments. No ads. No leaderboard upsell.
05Built on your data

Smarter because of you.

Domestique, segment leaderboards, route discovery, peer comparisons - they exist because athletes upload to Neverchill. Your training fuels a platform that gets sharper for everyone, including you. You stay in control of who sees what, and you can take your full archive with you any time.

  • Per-activity audience picker - public, followers, close friends, coach, private
  • Domestique learns from how strong athletes actually train
  • Export your full archive any time - FIT, GPX, JSON
  • Public read/write API on the 2026 roadmap
  • Deleting your account deletes your data - no 90-day "retention" loophole
