Brooks Beast GTS 24 vs Brooks Beast GTS 26:
Which to Choose
Verdict
These are two versions of the same idea, so the upgrade decision comes down to distance and feel rather than any dramatic gap in ability. Move to the 26 if you want a softer, taller, marathon-capable ride with a higher heel drop that spares the calves; stick with the 24 if you run half marathons and shorter, prefer a firmer and more grounded platform, and like its lower 8mm offset and structured upper. Either way you get the same maximum motion control and the same substantial weight — the 26 is simply the plusher, longer-legged evolution of a formula the 24 already nailed.

Who Should Choose Each Shoe
Choose
Brooks Beast GTS 24
Choose the Beast GTS 24 if your longest efforts top out around the half marathon and you prefer a slightly firmer, more grounded feel with a lower 8mm drop and a structured, secure mesh upper that locks the foot down. It's the pick for the overpronator or heavier runner who wants serious motion control on daily and long training miles without the extra stack and softer, more forgiving underfoot feel of the newer model. If you own it, run steady 10K-to-half distances, and love how planted it feels, there's no urgent reason to move on.
Choose
Brooks Beast GTS 26
Choose the Beast GTS 26 if you're pushing distance into the marathon or logging bigger weeks and want the extra protection of a taller stack and softer, pillowier nitrogen-infused foam. The higher, roughly 10mm heel bias suits runners who feel calf or Achilles strain and want that load eased, and the plusher knit upper and reworked GuideRails make it the more comfortable long-haul option. For a current Beast GTS 24 owner, the upgrade makes the most sense if you want a softer ride, more marathon-ready cushioning, or a bit more give underfoot.
Head-to-Head
Start with what's identical: both are max-stability (6/6), motion-control shoes with GuideRails, no plate, and cushioning rated high (5/6), and both are genuinely heavy — right around 350g in a men's US 9 — so neither is eager to accelerate. That heft is the point; it's the cost of this much structure. Where they diverge is in the details. The 26 moves to a nitrogen-infused DNA LOFT v3 that runs softer and more pillowy than the 24's already-plush foam, riding on a taller platform of roughly 38mm at the heel versus about 36mm in the 24 — a couple more millimeters of foam underfoot. The geometry shifts too: the 24 sits at an 8mm drop, while the 26 measures closer to 10mm (Brooks lists it higher still), giving the newer shoe a more traditional heel bias that takes a touch of load off the calves and Achilles. Neither is bouncy — both prioritize soft, controlled, planted transitions over rebound and pop — but the 26 is the plusher, more protective of the two, and Brooks reworked its GuideRails to be taller and narrower, keeping the correction closer to center. That, plus the softer foam and taller stack, is why the 26 stretches its comfort zone out to the marathon, whereas the 24's sweet spot tops out at the half. The upper changes character as well: the 24 uses a structured engineered mesh that feels secure and locked-down, while the 26 switches to a softer, plusher engineered knit.
