Intervals.icu

Everyone knows that the best way to improve as a cyclist is to do power based interval training. However its not always easy to motivate yourself to ride halfway up and down the same hill 8 times in a row. Intervals.icu automatically detects intervals so you can ride your favourite route, punish the rollers and still get good stats to track your progress. Forgot to hit the lap button? No problem!

Features

• Automatic interval detection in rides with real power data
• Comprehensive stats for each interval (power, heartrate, w/kg, torque, cadence, intensity, power zone etc.)
• Automatic grouping of similar intervals with average stats for the group
• Ride timelime chart showing power, cadence, heartrate, torque, training load etc. that highlights intervals with zoom
• FTP estimation from a single 60s+ maximal effort (no tests!), with training load based decay
• Ride power page with time in zones, power histogram, power curve (with season curve) and best power/duration efforts
• Athlete power page with power curve (for last 42 days, season etc.), FTP estimation, best power/duration efforts, power models
• Automatically detects and fixes power spikes
• Manual editing of ride data is also supported
• Comparison chart comparing intervals to similar intervals in previous rides
• Calendar style training log with interval summaries and weekly stats (training load, time in power zones etc.)
• Training load automatically estimated for HR only rides from previous rides with HR and power
• Performance management / fitness chart tracking fitness, fatigue and form over time
• Uses the standard Coggan metrics
• Email notification when you achieve new best power/duration efforts and when your FTP increases
• Download ride data in CSV format

Heartrate based interval detection is under development.
