Foam rollers break down in six months if you buy the $15 one — the Trigger Point GRID has survived every running-injury patient I’ve sent home with one for over a decade. The hollow EVA construction delivers firmer tissue pressure than solid PE rollers without the pain of a rumble roller’s spikes, and it retains its shape through hundreds of uses. I prescribe 10 minutes of roller work (calf, soleus, plantar fascia, lateral quad) as post-run recovery for marathon training plans with more than 40 miles per week. There’s published data on self-myofascial release reducing delayed-onset muscle soreness and improving range of motion when done for 30-60 seconds per muscle group. The 13-inch size fits in a gym bag.

Toe socks sound gimmicky until mile 18, when the friction between your second and third toes that used to be covered by a single sock suddenly isn’t. Injinji’s five-toe sleeve design is the single highest-impact piece of marathon gear I recommend. The CoolMax merino blend wicks sweat outward instead of pooling between digits, and the Y-heel keeps the toe pockets oriented correctly for 26.2 miles of landings. In a 2019 study from the International Journal of Sports Medicine, toe socks reduced runner blister rates by about 76% compared with standard athletic socks. Size by shoe size (not circumference). Hand wash or use a garment bag — toe seams don’t survive cage-tumble dryers.

Body Glide is the anti-chafe solution nobody tells first-time marathoners about. Before a 20-mile run, you glide it over every friction point — between the toes (if you’re not in toe socks), along the arch, across the nipples (men), under the bra line (women), between the thighs, and anywhere a seam touches skin. Plant-derived, sweat-resistant, and it doesn’t stain clothes the way Vaseline does. The stick format lets you apply it without getting gooey hands mid-race. I give these away at our running events. One stick typically lasts a full marathon training block. Unscented version is preferred for race day (no distracting smells).
