The capabilities that define Ridium. Each with its own detail page and help guide.

F / 01Free

AI Cycling Coach

A cycling coach that already knows your training β€” chat with an AI that reads your real fitness, fatigue, and calendar from Intervals.icu and answers like a coach, not a chatbot.

  • It knows your numbers before you ask. CTL, fatigue, FTP, and your next races are already in the conversation.
  • Workouts land in your calendar. Ask for a session and push it to Intervals.icu with one click.
Chat conversation: a fitness question + answer citing real CTL/TSB numbers (demo).
F / 02Free

Annual Training Plan

Build a season plan around your races β€” periodized blocks and weekly targets, created in a conversation and written straight into your Intervals.icu calendar.

  • Real periodization, not a template. Base, build, peak, and taper around your A/B/C priorities.
  • Included in Free. Season planning is not paywalled.
The annual plan card: blocks timeline with phases and race markers (demo season).
F / 03Free

Intervals.icu Integration

Ridium plugs into Intervals.icu β€” the data platform serious cyclists already use β€” so your coach works on your real rides, wellness, and calendar from day one.

  • One connection, everything follows. Profile, CTL/ATL/TSB, activities, power, and calendar.
  • Two-way where it matters. Plans created in Ridium are written back to your calendar.

Season Analysis

See what actually built your form β€” multi-year analysis of load, intensity, and peaks that turns seasons of ride files into decisions for the next one.

  • Compare seasons side by side. Volume, intensity, and peaks year over year β€” at a glance.
  • Feeds your next plan. Planning starts from this analysis: evidence, not vibes.

Race Simulator

Know your finish time before the start line β€” a physics engine that rides the actual course profile with your power, weight, and equipment.

  • Real physics, not a formula. Gravity, rolling resistance, aerodynamics, and descents, segment by segment.
  • Ride the Tour. Set your time on real Tour de France stages and compare yourself against the pros.
Results view: finish time + per-section times over the elevation profile.
