Cora for Cyclists
The AI Fitness Coach for Cyclists
You think in watts per kilogram. You know your FTP. You know the difference between a Zone 2 endurance ride and a tempo ride, and you know which one you're actually doing when you look at your power data afterward. You've probably bonked at least once and learned your lesson about fueling. Cora is built for cyclists who train with data — with AI coaching that understands the structure, language, and science of serious cycling training.
What Cora does for cyclists
Cora connects to your wearable (Garmin, Apple Watch, Wahoo via Health, or any Apple Health-connected device) and builds FTP-anchored training plans with precise zone prescriptions. It tracks your training load using a TSS-analog model (CTL, ATL, and form), uses morning HRV to guide daily intensity decisions, builds long-ride fueling plans, and periodizes your training around your race calendar — whether you're targeting gran fondos, crits, century rides, or competitive climbing events.
Key features for cyclists
FTP-based training zone calibration
Your FTP is the foundation of scientifically structured cycling training. Cora anchors all training prescriptions to your current FTP, setting precise zone targets for recovery rides (Zone 1), aerobic endurance (Zone 2), tempo (Zone 3), threshold (Zone 4), VO2 max (Zone 5), and anaerobic efforts (Zone 6). As your FTP improves — and it will — Cora updates your zones so you're always training at the right intensities relative to your current fitness.
TSS-analog load tracking
Cora accumulates your training stress across sessions into a comprehensive load model analogous to TSS/CTL/ATL (the system popularized by Training Peaks). You can see your chronic training load (your long-term fitness trend), acute training load (your current fatigue state), and your form — the difference between your fitness and fatigue that predicts whether you're primed for performance or need recovery. This is the same framework elite cyclists use to manage their training year.
Climbing vs. TT periodization
Cycling performance goals aren't uniform. Cora supports goal-specific periodization for cyclists targeting different race types: climbing-focused plans that emphasize W/kg development and body composition alongside absolute power; TT-focused plans that prioritize FTP development, pacing precision, and position sustainability; criterium and road race plans that develop anaerobic capacity and repeatability. Your race calendar drives the periodization emphasis.
Long-ride fueling guidance
Bonking on a long ride is preventable. Cora builds your fueling plan for rides over 90 minutes — carbohydrate intake per hour calibrated to ride intensity, fluid and electrolyte targets based on expected sweat rate, and pre-ride meal timing. For race days or peak training blocks, Cora provides specific carbohydrate-loading guidance to maximize glycogen stores going into your most important efforts.
HRV-guided training adaptation
Cycling training creates substantial fatigue that accumulates over days without always feeling acute. Cora uses your morning HRV to detect systemic fatigue — particularly the declining HRV trends that precede performance stagnation and illness — and adjusts your session targets before you dig yourself into a hole. A planned threshold session becomes a recovery ride when your readiness score signals you won't get the intended adaptation from hard work.
The science: why power-based training works and where Cora adds value
Power-based training works because power output (measured in watts) is the only direct measure of your actual work rate on the bike. Heart rate lags behind effort, is affected by heat, caffeine, and fatigue, and doesn't directly measure mechanical output. Power, normalized to your FTP, tells you exactly how hard you're working relative to your current fitness — and this is the basis of every serious cycling training system in use today.
The TSS (training stress score) model, developed by Andrew Coggan and popularized by Training Peaks, quantifies training load by combining duration and intensity into a single number. Accumulating TSS builds chronic training load (CTL — your long-term fitness), while short-term TSS accumulation creates acute training load (ATL — your fatigue). The difference between them is your "form" or "freshness". Cora uses this framework to help you understand when you're building, when you're fatigued, and when you're primed for peak performance.
Where Cora adds value beyond a pure power-based system is in the recovery layer. Traditional cycling training software tells you your training load numbers but doesn't know whether you slept well, what your HRV looked like this morning, or how yesterday's threshold session actually landed physiologically. Cora combines the objective load tracking of power-based training with the physiological insight from your wearable data to make better daily decisions — whether today is a day to execute the planned threshold session or a day to drop it to Zone 2 and protect your ability to train hard tomorrow.
For fueling, the research from sports nutrition science is clear: carbohydrate availability is the primary limiter of sustained high-intensity cycling performance. The guidance has evolved from 60g/hr to 90g/hr (using multiple transportable carbohydrate sources) for efforts lasting over 2 hours, with research showing performance benefits up to 120g/hr in trained athletes. Cora builds your fueling recommendations around these evidence-based targets.

Frequently asked questions
Does Cora track FTP-based training zones for cyclists?
Yes. Cora uses your FTP (functional threshold power) as the anchor for all cycling training zones — from Zone 1 recovery riding all the way through Zone 6 anaerobic work. If you've done an FTP test recently, enter your result and Cora calibrates all your zone targets accordingly. If you haven't tested recently, Cora can help you estimate your FTP from ramp test protocols or from existing ride data. As your fitness develops, Cora prompts you to retest FTP to keep your zones accurate.
How does Cora handle periodization for cycling — climbing focus vs. TT focus?
Climbing performance and time trial performance are related but emphasize different physiological qualities. Climbing primarily rewards high W/kg (power-to-weight ratio), which means developing both absolute power and minimizing non-functional body weight. TT performance rewards high FTP relative to aerodynamic position and body position sustainability over sustained durations. Cora builds training phases that address both requirements, with the balance determined by your race calendar and stated event priorities. A rider targeting mountain gran fondos has a different emphasis than one targeting flat crits.
Can Cora help with long-ride fueling strategy?
Yes. Long-ride fueling is one of the most impactful performance variables cyclists have direct control over, and research is unambiguous: underfueling on rides over 90 minutes significantly impairs performance and recovery. Cora builds your fueling plan based on your ride duration and intensity — targeting 60-90g of carbohydrate per hour for moderate-to-hard efforts, appropriate fluid and electrolyte targets based on weather conditions, and pre-ride meal timing guidance. It also tracks your post-ride recovery nutrition to ensure you're replenishing glycogen adequately before your next session.
Does Cora track TSS (training stress score) or a similar load metric?
Cora uses a training load metric analogous to TSS — combining session duration and intensity (using your FTP-relative power zones as the intensity anchor) to generate a composite training stress value for each ride. Like TSS, this allows Cora to accumulate and compare training load across sessions of different durations and intensities, track your chronic training load (CTL, your fitness), acute training load (ATL, your fatigue), and form/freshness (the difference between the two). You don't need a power meter — Cora can use heart rate as an intensity proxy — but a power meter gives you the most accurate load estimates.
How does Cora use HRV for cyclists specifically?
HRV is particularly valuable for cyclists because cycling training is high in volume (many hours per week) but relatively low in muscle damage, meaning subjective fatigue often doesn't reflect systemic recovery state accurately. You can feel okay but be significantly underprepared for a quality session because of accumulated training load from previous days. Cora uses your morning HRV to detect this hidden fatigue — particularly a declining HRV trend across a training block — and adjusts your session targets accordingly. A suppressed HRV on a planned threshold day might shift Cora's recommendation to a recovery ride instead.
