Trail Race Kit Test 2026: Seven Pieces of Running Gear Put to the Test

Introduction

Testing gear in a real race beats any lab session, so a hilly trail half marathon on the South Downs was the perfect opportunity. On the menu: a pair of carbon-plate trail shoes from a brand making its move westward, a new cap, race shorts with serious storage, trail-friendly socks, affordable sunglasses, open-ear headphones, and, unexpectedly, a car seat towel that turned out to be the highlight of the day. Here is how each piece held up over around 500 meters of climbing and nearly two hours on mixed trail.

The Race: House Dean Half

The House Dean Half is part of the South Coast series and offers both a half marathon and a 10K across the South Downs near Brighton. Much of the route follows the South Downs Way, supplemented by public footpaths across fields and some rockier, more technical single-track where you need to watch your footing. With everything dry in mid-summer, the hard-packed paths allow a good pace, and the second half features some fast downhills to recover time lost on the big climbs.

Organization at the start was solid. Pre-race information on the website includes course videos and explanations of how everything works, parking was free and stress-free, and the event village had plenty of seating plus indoor warehouse space for sunny days. The finish line area is equally generous, with food, drinks, sweets, and a coffee stand.

Two caveats worth knowing before signing up. First, there were very few marshals on the course beyond the three water stations, and some faster runners took a wrong turn and added extra distance, so more course marshalling at tricky sections would help, especially if you do not know the South Downs. Second, there is no designated car park, just roadside parking on a country lane, which was fine with a couple of hundred entrants but could become a problem if the event grows. The course itself sits around 500 meters of elevation, with most of it early on, so expect a demanding but rewarding run.

Kailas Fuga X Pro Trail Running Shoes

The main test of the day was the Kailas Fuga X Pro, a performance trail shoe from Kailas, a Chinese brand that is huge at home and now pushing into Western markets. After a week of easy runs on the downs, faster sessions on footpaths, and this race, the impression is very positive. It feels like a well-balanced performance trail shoe: comfortable, stable, and rolling nicely across varied terrain, with foam that carries plenty of energy despite not being an especially light shoe.

The carbon plate design is a differentiator. Rather than a full-width plate, it uses an X-shaped layout that adds stability while keeping flexibility, so the shoe feels more natural than many carbon trail shoes. It never feels aggressive or like it is forcing your foot into a rigid position. Uphills feel good, downhills stay stable without wobbliness, and on the road kilometer at the end of the race it transformed into a bouncy, fast road shoe. A full review is coming, but as a race-day first impression, this one is exciting.

Grassmi Cap

The Grassmi cap, in the Spring Verdant design, is an early run of a new hat and was worn for the first time during this half marathon. It is a solid, comfortable cap that felt very nice on the head for the whole distance. The design is understated with subtle detailing, which suits runners who prefer muted colors over loud neon. If you like your running headwear quiet and well made, this one ticks a lot of boxes, and more versions are apparently on the way.

Salomon Proto Lab Advanced Marathon Shorts

The Salomon Proto Lab Advanced Marathon shorts are a modern take on old-school split shorts: extremely lightweight and thin, built for running fast. Where they differ is storage. The back features zip pockets for small items like keys, plus gel loops and pockets that can carry around four gels according to the product page. On the run, they are barely noticeable on the legs. If you normally prefer a liner, that is worth considering, but if you want the lightest possible race short without giving up fuel storage, these are a great option.

Versus Active Socks

The Versus Active socks need little introduction beyond this: they are really good. Comfortable, with a nice design and a sensible balance of padding. They are not as thin as typical race socks, which is welcome on trails where a bit more cushioning helps fill out the shoe, yet they never feel overly thick. No blisters over the whole trail course, which is the ultimate test for any running sock.

Goodr Bolt Gs Sunglasses

Goodr keeps pushing the boundaries of affordable shades, and these are a new colorway of the Bolt Gs. They sit in the performance-oriented part of the Goodr range, with various models offering different lens options and widths, but all around a similar accessible price. On the day they were lightweight, simple, and comfortable, with great visibility in the patchy sun. They stayed firmly on the head with no bouncing at all. For anyone who wants capable running sunglasses with a more subtle look than full-on performance styles, the Bolt Gs are an easy recommendation.

Sunto Spark Headphones

The Sunto Spark headphones were tested a few weeks earlier at a busy 10K, where they proved too quiet to enjoy music over crowd noise. On quieter trails they worked much better. The sound quality itself is genuinely very good, and they fit comfortably. There are some frustrations, though: there is very little control available on the headphones themselves, and an automatic volume-limiter safety feature repeatedly drops the volume, claiming levels are dangerous even though these headphones are not especially loud, with no obvious way to disable it. For trail runs in calm conditions they work well, but they are less suited to loud, busy streets.

Sprint Car Seat Towel

The strangest item on the list was also the most impressive. The Sprint car seat towel is essentially a very large microfiber towel that hooks over the top of your car seat and covers the whole seat. It solves a familiar problem: getting back to the car soaked in sweat after a hot run, or drenched after a wet winter session, with no spare clothes. Because it is microfiber, it absorbs the moisture without letting it drip through to the seat underneath. It rolls up small, so it can live in the car permanently. For anyone who drives to training sessions or races, this is a genuinely clever bit of kit.

Overall Buying Advice

Every item tested here performed its job well on race day, so the choice comes down to what you actually need. If you want one performance upgrade, the Kailas Fuga X Pro is the standout for mixed-terrain trail racing. If your priority is staying comfortable in summer heat, the Goodr Bolt Gs and Versus Active socks cover visibility and blister-free feet at accessible prices. Racers chasing every gram should look at the Salomon Proto Lab Advanced Marathon shorts. The Sprint car seat towel is the sleeper pick: inexpensive, unglamorous, and arguably the most immediately useful item of the lot. The Sunto Spark headphones are best saved for quiet trails rather than loud events.

Conclusion

The House Dean Half proved to be a great testing ground: a tough, scenic South Downs course with good pre-race information and a welcoming event village, held back mainly by sparse on-course marshalling. The kit, meanwhile, passed with almost no complaints, from the versatile carbon-plate trail shoes to the humble car seat towel. Few pieces of gear failed to earn their place, and several earned a permanent spot in the race bag.
