Rust Sprint Changes: Sprint Effort Armor Stat and Hunger Cost

Sprinting in Rust got a little more expensive in the November 5 update: it now raises your hunger and thirst use by 10%. New Facepunch commits show a bigger change after that, where the armor you wear decides how much extra food and water a sprint costs.

The flat 10% is live now. The armor based rework is work in progress on its own branch, and its numbers are marked as not final. Facepunch has not given it a date.

What changed in the November update

The Printed and Polished patch notes list one simple line: sprinting now increases hunger and fluid consumption by 10%. Our patch notes summary covers the rest of that update.

The number moved before it shipped. On November 4, Jarryd Campi cut the default sprint bonus to +10%, down from +25%. So the version that went live is the gentler one.

For most players this is a small tax. If you run everywhere, you will eat and drink a bit more often. It is worth keeping some food in your hotbar on long runs to monuments.

The next step: a Sprint Effort armor stat

On November 5, Jarryd Campi pushed a reworked sprint metabolism system to a branch called sprint_metabolism_changes_dec_26. The commit says it is for the next wipe, and that today's wipe only has the flat 10% penalty.

Here is what the commit describes:

• The sprint metabolism scale goes up to 1.3, which the commit calls 30%.
• How much of that you pay now depends on a new stat on armor, called Sprint Effort.
• Sprint Effort is added to the heavier armor pieces: roadsign, heavy plate and ballistic.

The commit then lists work in progress values for full sets:

What you wear	Sprint penalty
Metal facemask, metal chest plate, roadsign kilt and roadsign gloves	100%
Heavy plate set	100%
Ballistic set (helmet, vest and legs)	75%
Wood armor set	40%
Naked, burlap or cloth basics	No penalty at all

Our reading of this: the 100% sets pay the full extra cost from the 1.3 scale, and light clothes pay nothing extra. This is our guess at how the two numbers combine, since the commit gives the scale and the percentages but no worked example.

Why it matters

Right now everyone pays the same 10% when they sprint. Under the rework, gear choice would matter. A fully kitted player in heavy plate or a roadsign set would burn through food and water faster when they run. A fresh spawn in cloth would not pay the extra cost at all.

In other words, heavy armor would cost you food and water on top of the protection it gives. It may also make cheap food like the new apples and coconuts from the November fruit trees a bit more useful for geared players. For a refresher on food basics, see our farming guide.

The branch name ends in dec_26. That is our guess that Facepunch is aiming at the December 2026 update, but the commit itself only says "next wipe", and values can still change before it ships.

Other survival changes in the commits

Two more commits from the same week touch daily survival. Both are on their own branches and are work in progress.

• Stashes now decay. On November 4, Adam W fixed stashes not decaying and added a server setting for how long it takes. The commit does not name the setting or give the default time. If it ships, old hidden stashes may stop lasting forever.
• Food in loot containers stays fresh. Jarryd Campi made it so food in loot containers no longer spoils until the container is looted for the first time or the item is taken out. The commit names apple trees as the case. It also adds a command, tree.spawn_with_additions, that spawns a tree with its honey and apples.

FAQ

Does sprinting make you hungry faster in Rust? Yes. Since the November 5, 2026 update, sprinting raises hunger and fluid use by 10%.

What is Sprint Effort in Rust? A new armor stat in the commits. It sets how much extra food and water sprinting costs, based on what you wear. It is not live yet.

Which armor will cost the most to sprint in? In the work in progress values, heavy plate and the metal and roadsign set are at 100%, ballistic at 75%, wood at 40%, and cloth has no penalty.

When will the Sprint Effort change come out? There is no date. The commit says next wipe, and the branch name hints at December, but that is our guess.
