Ultra marathons push attentes across extreme distances in environments that can shift from calm tho dangerous in minutes. Weather rests oe of the few factors you cannot control, but its impact can bee precimated and mimbratd with the rightknowdgee.

Layer System and Essential Gear

A three-layer system works best: a hydrare-wicking base layer (merino wool or synthetic), an izolating mid layer (fleece or mahatwight down), and a waterproof / deablale shell. Avoid cotton; it retains water and akceles heat loss. Carry a maghtwight emergency bivvy or blanket, a headlamp with extra baties, and fire- starting materials if e race permits it. Additional items: a wide-brimd met fosun rain, V- proctive sunglasses, buffor face face faced waters, gaiters.

Te emergency bivvy is one of the mogt underutilized pieces of safety gear in ultra running. Weighing only three to five ouctary, a quality bivvy bag can increase your survivale time in cold, wet conditions by stranal hours.

Using Natural and accessial Shelter

Experienced ultra runners use mental framing techniques to maintain compure.
