Trail Race Kit Roundup: Apparel, Nutrition, Tech and Shoes for a Long Day on the Trails

Introduction

When a race involves running the same loop for 12 hours, kit choices matter in a slightly different way than for a point-to-point ultramarathon. You are never far from your drop bag or a checkpoint, so the emphasis shifts from carrying everything to choosing things that stay comfortable hour after hour. This roundup covers the apparel, nutrition, tech and shoes we picked for our longest race of the year, a looped trail event on farmland in Hertfordshire. Every item here earned its place for a specific reason, and the same logic should help you build your own race kit list.

Say Sky Race Apparel

Danish brand Say Sky takes care of most of the apparel for this race, drawn from their latest flow range. The Flow Combat Tee is a lightweight, breathable technical top, which suits a forecast that mixes a showery morning with a warm, humid afternoon. Both of us will be wearing one, partly for comfort and partly so we can spot each other easily on every lap.

Shorts differ by preference. The Pace 5” Shorts hit a sweet spot for longer distances if, like many runners, you find very short shorts uncomfortable over 12 hours. The Combat Short Tights offer a more fitted option that works well for racing, and the Flow Combat Cap completes the matching look along with a pair of matching socks.

Hydration and Layers for a Looped Course

With a checkpoint every 5.2 km, a full race vest is not required at the start. A running belt with a small soft flask and a couple of gels covers the early hours. The Say Sky 12L Flow Vest comes into play later in the event: once fatigue sets in, loading it with two soft flasks and snacks means never having to stop running between laps.

The Element 3L Waterproof Jacket is packed just in case, for a wet start and a potentially chilly 8 a.m. beginning. It is a good example of the looped-race logic: light enough to carry all day, valuable if the morning turns.

Precision Fuel & Hydration Nutrition Plan

For a 12-hour effort, nutrition strategy matters as much as shoes. The plan combines standard gels, which suit a runner who finds caffeine upsets the stomach mid-run, with sports chews for variety. The chew bars are the standout: at 68 g with 60 g of carbs, they pack serious energy into an easy-to-digest format with a pleasant consistency.

One lesson from previous looped events shapes the rest of the plan: after four or five hours, sugar alone starts to lose its appeal, so savoury food like ready-salted crisps and salted peanuts goes in the bag too. On the hydration side, one 1000 electrolyte tab goes into a soft flask, with the plan of running one 500 ml flask with electrolytes and one with plain water once the vest is on, plus a few salt tablets as backup for hot, humid conditions. For a salty sweater, that mix is sensible insurance.

Tech: Coros Pace Pro

The Coros Pace Pro handles tracking for the day. Its AMOLED display is genuinely bright and colourful, and very easy to read on the move, which matters when you are glancing down mid-run for hours. The onboard mapping and navigation will barely be needed on a looped course, but one feature will earn its keep: a recurring alarm every 45 minutes as a reminder to take on nutrition, because the first hours of a looped event pass surprisingly quickly and calories are easy to forget.

A free lightweight nylon band accompanies new watch purchases through the brand’s current offer, and it is a worthwhile addition. The band is comfortable over long hours and simple to fasten and unfasten, even with tired hands.

Race Shoes: Inov-8, La Sportiva and VJ

Shoe choices split cleanly here. The Inov-8 TrailFly Max is the pick for the marathon, following a strong track record with the standard TrailFly across major ultras. The Max version has not come off her feet since arriving, thanks to generous cushioning and an upper that suits her foot shape.

For the 12-hour challenge, two pairs of shoes get their first real test. The plan is to run the first half in the La Sportiva Prodigio Pro, then switch to the VJ Ultra 3, mainly because underfoot conditions on the farm route are unknown. By the finish each pair should have around 100 miles on them, setting up a proper head-to-head comparison.

Overall Buying Advice

The through-line in this kit list is comfort over duration rather than speed over distance. For apparel, breathable technical fabrics beat heavier layers when a warm afternoon follows a showery morning. For nutrition, alternating sweet and savoury foods and mixing electrolyte and plain water flasks helps you keep eating when sugar fatigue sets in. For tech, the most valuable features are often the simple ones, like a repeatable nutrition alarm and a readable display. And for shoes on an unknown route, carrying two options beats guessing wrong on grip or cushioning. Match your kit to the format of your race and the forecast, and most of the usual mid-race discomforts disappear.

Conclusion

A looped race removes the need for a full mandatory kit list but raises the bar on everything you do wear or carry. This selection covers lightweight Say Sky apparel, a flexible Precision Fuel & Hydration nutrition plan, the Coros Pace Pro for pacing and reminders, and three trail shoes with clear roles. If you are building a kit list for a long day on the trails, the same categories and reasoning apply, whatever the brand names on your gear.
