Getting somewhere should be the easy part of colonizing a planet. Great alongside Tough Colonist when you want to run headfirst into trouble and actually get there.

</>Common questions about Cardio Day (Endless Stamina)
What does Cardio Day do in Occupy Mars: The Game?
Cardio Day stops your stamina from draining in Occupy Mars: The Game, so you can sprint and jump for as long as you like without stopping to recover. Mars is enormous, and the default rhythm of run-a-bit, pant-a-bit turns every trip between dig sites into a slog. With Cardio Day switched on, that pause disappears and you simply hold sprint until you arrive. Toggle it off any time and your stamina bar goes right back to behaving normally. It's one of the simplest quality-of-life boosts in the Occupy Mars collection on ProjectMods.
Does Cardio Day affect jumping as well as sprinting?
Yes. Anything in Occupy Mars: The Game that normally eats into your stamina bar stops costing you, so repeated jumps are just as free as an endless sprint. That matters more than it sounds on Mars. Hopping up rock shelves, bounding across broken terrain and chaining jumps to clear a crevasse are all things the vanilla stamina budget quietly discourages. Cardio Day removes the budget entirely. You can leap your way up a canyon wall instead of walking the long way around, and you'll never land at the top with an empty bar and nowhere left to go.
Do I still take fall damage or other hazards with Cardio Day on?
Yes, because Cardio Day only touches stamina in Occupy Mars: The Game. Sprint off a cliff and you'll hit the ground exactly as hard as you would in vanilla, and radiation, oxygen, hunger and thirst all keep ticking normally. That's deliberate. It's a movement boost, not a survival blanket. If you want to sprint into genuinely dangerous places and come out the other side, pair Cardio Day with Tough Colonist so the falls stop hurting and Endless Air so the tank never runs dry while you're out there covering ground.
Can I turn Cardio Day off mid-run?
You can. Cardio Day is a straight toggle in the ProjectMods launcher, so flip the card off whenever you want your stamina bar back and Occupy Mars: The Game returns to normal draining right away. No restart, no save reload, nothing permanent written into your colony. Leave it on for the long haul between outposts, then switch it off once you're back at base and want the survival pressure again. Because it's reversible, it's also an easy one to try for a single expedition and drop if you decide you miss the pacing.
Why would I use Cardio Day instead of just walking?
Because Occupy Mars: The Game puts all the good stuff a long way apart. Dig sites, ore deposits, crashed supply pods and your own remote outposts are separated by kilometers of red rock, and the stamina bar turns that distance into a stop-start commute rather than an adventure. Cardio Day makes travel the easy part of colonizing a planet, which is kind of the point. The fun is in what you build when you arrive, not in the panting. Builders and anyone running a sprawling multi-site colony feel it immediately, and it pairs naturally with Power Walker and Red Planet Rocketeer.
