Now that I’m a third of the way through 75 Hard, it’s time to talk about the thing everyone brings up first: the 75 Hard water requirement. And honestly, after 25 days into the challenge, I get it.
Drinking 1 gallon of water a day is by far one of the most-failed daily tasks in this popular challenge.
It’s a lot of water even for someone who is active. And if you’re a smaller person, the baseline for water intake is lower.
What surprised me is how much strategy the 75 Hard water rule actually takes. It’s more a logistic challenge than a mental one. I have to plan my water intake around the availability of washrooms. I have to be especially mindful of my water intake before I head to the mountains. (I’ve had a few near misses).
My daily rhythm after 25 days
I can easily drink one litre of water within the first few hours of waking. Our bodies crave hydration in the morning after a night’s sleep, and I feel good if I’m on my second one-litre tumbler of water by mid-morning.
I drink the second litre by 2 p.m. or earlier. It really depends if I’m training at the gym or if I’m running that day. I’ve learned not to drink too much water before I go running especially within Calgary.
I like to finish the one gallon of water at the latest 7 p.m. But sometimes it doesn’t always go according to plan. Some people complain about having to get up to use the washroom at night but I haven’t had that issue.
This my seem fairly obvious, but the more active I am, the more easier it is to drink all that water.
I’ve also noticed that sipping water is better than guzzling it.
What I’ve noticed in the first 25 days
I am taking frequent trips to the washroom than I was at the start of the challenge. Before the 75 Hard water challenge, I was clearly dehydrated. My skin looks better and I feel more focused.
I may not keep up a full gallon a day once the challenge ends, but I do plan to stay more intentional about hydration.

The first 25 days of 75 Hard are a relentless test of discipline, mental fortitude, and physical endurance, with water playing a surprisingly central role. This program demands two daily workouts, one outdoors, strict dieting, daily progress photos, and, crucially, drinking a gallon of water each day. The water requirement, while seemingly simple, becomes a constant companion and challenge. It forces mindfulness around hydration, turning a basic necessity into a structured habit. Carrying a gallon jug becomes second nature, and the frequent trips to the bathroom serve as reminders of the commitment. The water also aids in recovery, flushing out toxins, and maintaining energy levels during the grueling workouts. By day 25, the physical changes are noticeable—increased stamina, leaner physique, and clearer skin—but the mental transformation is even more profound. The act of consistently meeting the water goal, alongside the other demands, builds an unshakable sense of self-efficacy. Water, often overlooked, becomes a symbol of resilience, proving that even the smallest, most consistent actions can lead to monumental change
