About lockd | triathlon trainingsapp
A triathlon plan that fits the time you actually have. Answer a short questionnaire: which distance, when your race is, how many hours a week you have and which days you can train. lockd builds your full plan, from today to race day. WHAT YOU GET • A periodised plan: base, build, peak and taper, with a recovery week every fourth week. • Every session written out in blocks: how long, which zone and why you do it. • Sprint, olympic or 70.3, matched to your level per discipline. • Your weakest discipline gets extra attention. • Strength training on top of your hours, if you want it. WHILE YOU TRAIN • Live GPS recording: time, distance, pace and your splits. • Your blocks count down on screen, so you know when it gets hard. • Recording continues when your screen goes off. • You can also log a session afterwards, in seconds or in hours and minutes. KEEPING TRACK • See your week, your volume per discipline and your records at a glance. • Apple Health: completed sessions go to Health, and workouts you record with your watch check themselves off. • Reminders the evening before and on the day itself. WHAT THE PLAN IS BUILT ON Periodisation, roughly eighty percent easy and twenty percent hard, recovery built in, and never two hard days in a row. The same principles coaches use, applied to the hours you have. lockd is available in English and Dutch, and follows your phone's language. SUBSCRIPTION Your first training week is free. After that a subscription unlocks the rest of your plan. • lockd monthly - EUR 6.99 per month • lockd yearly - EUR 59.99 per year New subscribers start with a 7-day free trial. Payment is charged to your Apple account. A subscription renews automatically unless you cancel at least 24 hours before the end of the current period, in your Apple settings. You can cancel there at any time. Terms of use: https://locd.vercel.app/voorwaarden Privacy policy: https://locd.vercel.app/privacy lockd provides general training advice and is not a medical device.

What’s new
Version 2.0 · Updated October 27, 2026
lockd 2.0: a new look and more control over your season. • New design: from your plan to your stats, in dark and light. • Races: your season as a calendar with a countdown to your race, plus B races along the way such as a 10K, a sprint or a gran fondo. • Change race: new date, distance or name? Your plan adapts and your completed sessions stay. • Pool days: choose the days you can swim, and your swim sessions only go on those days. • Locked in: after every completed week, see how it went and what stood out. • Analysis without heart rate: see whether you got faster than your previous similar sessions. • Your own zones: enter your max heart rate and FTP for zones that fit you. • A tour right after your first plan, and everything easier to find.
