Wide landscape editorial photograph of a mountain biker mid-ride on a dusty red-orange singletrack trail in the South African Western Cape, golden hour light raking across the scene. The rider is in sharp focus on the right third of the frame, wearing a weathered cycling kit with a race number plate on the handlebars, dust kicking up from the rear tire. Behind them, rolling hills covered in fynbos shrubland and silhouetted protea plants fade into soft, hazy blue mountains. Warm amber sunlight creates long shadows and a soft rim light around the rider and bike.

In the lower left foreground, slightly out of focus, a small minimalist glass vial and a clear water bottle sit on a flat sun-bleached rock, with a few drops of liquid catching the light. Next to them, a simple matte paper notecard and a pencil suggest data collection, with no legible text. The vial and bottle are clean, understated, and modern, with no branding.

The color palette is earthy and refined: terracotta, ochre, sage green, dusty teal sky, and cream highlights. The composition uses shallow depth of field, a generous negative space in the upper left sky for headline overlay, and subtle film grain. The mood is contemplative, skeptical, and quietly sophisticated, like a feature photograph from a high-end outdoor sports and science magazine. Natural, candid, cinematic, shot on a 50mm lens with soft contrast and muted saturation. No futuristic elements, no glowing effects, no molecular graphics, no text.

Ketone IQ elevó los cuerpos cetónicos en el Cape Epic, pero no hizo nada más

BY DR. GYMBRO ·

Los ciclistas que compitieron en los ocho días del Cape Epic tomaron Ketone IQ dos veces al día y alcanzaron alrededor de 1 mM de cetonas en sangre, pero su fatiga, frecuencia cardíaca, tiempo de reacción y recuperación fueron idénticos a los del grupo placebo. El ensayo doble ciego evaluó R‑1,3‑butanodiol en condiciones reales de carrera, no en laboratorio. Los autores señalan que la leve cetosis no fue eficaz y advierten que el butanodiol no debe confundirse con los ésteres de cetona. Con solo 18 participantes, el estudio tiene limitaciones, pero constituye un dato sobrio para quien piense en invertir en una costosa bebida cetogénica para recuperarse.
