75-Day Hard Challenge Tracker

How this 75-day hard challenge tracker works

Press Start Challenge and Day 1 is today. No start-date field to fill in, nothing to sign up for.

Each day, tick all five tasks, then press Complete Day. The day only logs when every task is checked, which is rather the point: four out of five is not a completed day. Today's checkboxes reset at midnight, so a task you ticked yesterday will not carry over.

Three numbers move as you go: the day you are on out of 75, the number of days you have completed, and your completion percentage. That percentage is always out of 75 rather than out of days elapsed, so Day 38 completed clean reads as 51%, not 100%.

Strict mode is on. If an earlier day was never completed, the tracker stops you, clears the stored progress, and puts you back on Day 1. Everything lives in your browser's local storage, one device and one browser, with no account and nothing sent to a server.

The five daily tasks, in plain terms

Two 45-minute workouts. Two separate sessions, not one 90-minute block, spaced a few hours apart, and one of them has to be outdoors whatever the weather is doing. Banking both into a single gym trip is the most common way people quietly break the rule.

Follow your diet. You pick the eating plan; the rule is that you stick to it, with no cheat meals and no alcohol. Choose the plan before Day 1, because deciding what counts halfway through a Tuesday never ends well.

A gallon of water. One US gallon, roughly 3.8 litres, spread across the day. Counting it out as a set number of bottle refills is easier to track than drinking to a feeling.

Ten pages of a non-fiction book. Physical pages you read yourself. Audiobooks do not count, which catches a lot of people out on a long commute.

A progress photo. One a day, ideally at the same time and in the same spot. This is the one most likely to be forgotten at 11:50pm with the other four already done.

What the restart rule actually costs you

Do the arithmetic before you start. A miss on Day 60 does not cost you one day. It costs you 60, because the grid clears and the count goes back to zero. That is what the rule is for, and it is also why so many attempts end somewhere in the middle rather than near the start.

If it happens, a few things help. Restart deliberately, on a date you choose, rather than at 6am the next morning on a wave of frustration. Fix the task that broke instead of promising yourself more willpower: a missed outdoor workout in February is a scheduling problem, not a character problem. And work out in advance which of the five is your fragile one, then defend that one first each day.

Whether a bright-line rule is the right tool at all depends on the habit and on where you are with it. The guide on strict vs forgiving habit tracking works through when the all-or-nothing version helps and when it just costs you months.

When one habit beats five

Five tasks a day means five chances to lose the run, every day, for two and a half months. One habit means one decision, and a rule that survives an ordinary bad week rather than punishing it.

A shorter run also puts the finish line somewhere you can see it, before the novelty wears off. If that sounds like the better fit right now, the 30-Day Habit Challenge Tracker runs the single-habit version, and the 30-Day Challenge End Date Calculator puts your finish date and milestones on the calendar.

None of this is a better-or-worse comparison. The 75-day format is built to be demanding, and plenty of people finish it. The question is what you can hold for the length of the run you are picking.

LockIn30 runs the same idea on your phone: one habit per challenge, 7 to 365 days, strict or forgiving per challenge, with reminders, statistics, and progress photos that stack into a 1080x1920 timelapse. It stays on your device, with no account.
