Trailing running kit

Trail running provides a similar connection with nature and sense of flow to open water swimming. Here is some kit you might find handy…

FINDRA Etive Technical Fleece

£125

Pro: Lightweight with outstanding breathability
Con: A real investment for a mid-layer

I was so impressed with this technical long sleeve mid-layer, which is designed for high-output mountain activities. Although it’s called a ‘fleece’, it’s a super low-bulk and lightweight layer with a soft waffle feel. By lending natural wool with recycled nylon, the Etive promises to help you regulate your temperature and has long-lasting odour resistance; it even keeps you dry when damp from mist or sweat, yet it dries far faster than 100% wool alternatives. Flatlock seams eliminate shoulder chafing under a backpack or running vest, while the sleeves have low-profile thumb loops to keep your wrists warm. There’s also a hidden, small zip pocket on the rear flank for stashing valuables. I can tell I’ll be wearing this plenty over the summer. JT


Boldwill [PF39.Wood] T-Shirt

£57

Pros: Cool and comfortable with a good fit
Cons: Price. Too good for running?

The life of my t-shirts follows this pattern as they age: casual wear -> run wear -> bike cleaning rag. I wouldn’t normally buy a technical fabric t-shirt specifically for running. Happily, this technical Boldwill t-shirt is made from super soft Tencel Lyocell fabric, making it an item I want to wear for more than just running. It is probably the nicest t-shirt I’ve ever had in terms of fit, shape and comfort. For running, it was cool and comfortable, and absorbed much less moisture than my usual cotton t-shirts. I didn’t get any complaints about post-run armpit odour either. It did exactly what it’s supposed to do. It feels robust and refined, and hopefully many years away from bike cleaning duty. SG


FINISTERRE Solar UPF Long Sleeve Top

£65

Pro: The technical fabric is high wicking and keeps you cool
Con: Not a big thing, but thumb holes are a nice to have on a long sleeve top

A long sleeved top with UPF 50+ that works equally well for protecting your skin against the sun’s harmful rays while running or hiking, as well as pulling on over a swimsuit at the beach. The soft recycled polyester draws heat and moisture away from your skin to keep you cool and dry. It’s quick-drying, too, so it’s a great piece to pack for an active trip. The top fits true to size, with a relaxed regular fit, while raglan sleeves and flatlock seams allow you to move easily without the risk of it chafing on your shoulders – so it’s great for wearing with a backpack or running vest.

M&S Goodmove Ultraheat Funnel Neck Running Top

£26

Pro: A budget-friendly versatile layering piece
Con: The smooth fabric might be prone to bobbling over time

The inside of this half-zip running top is so incredibly soft! It feels lovely against your skin as you’re running but equally it’s an ideal post-swim layer as it’s breathable and has thermal qualities to add immediate warmth when your body needs it most. It also blocks windchill when you’re running without adding excessive bulk. Despite the thermal lining, it’s breathable, wicking moisture away from your skin so you don’t feel clammy and cold when you stop. Thumbholes keep the sleeves in place as you run and add extra warmth. A versatile layer for both swimmers and runners. JT


KEEN Roam Trail Running Shoe

£130

Pro: A hybrid shoe that transitions well between pavement and off-road trails
Con: Not waterproof so it’s not the best choice for muddy paths

I tried out these new trail running shoes on the South West Coast Path and they were exceptionally comfortable from the off with that springy feel that urges you forward – I actually ran much further than I anticipated because I could barely feel them. A high-traction grip and a cushioned outsole softened the impact of rocky paths, leaving me free to focus on glimpses of the sea through the trees. They’re not waterproof, but they’re lightweight and dry quickly. A great go-to trainer for trail running or trips to the coast when you want to do more than just swim. Available in men’s and women’s.

OSPREY Dyna Pro™ 7 Run Hydration Vest

£140

Pro: A pocket for everything
Con: High price point

Water, phone, sunglasses, hat, energy gels, a house key: when you’re trying to push your running distances, there’s actually a remarkable array of bits you might want to carry with you. This hydration vest, with a 7L capacity, tucks everything away neatly and comfortably. There’s a pocket for everything, which you can reach without removing the vest: a giant kangaroo-like pocket at the lower back to stash a rain jacket; four drop-in stretch mesh compartments at the front for snacks and inhalers; plus a vertical zippered pocket for keys and phone. Even with the two 500ml soft flasks filled up, the vest doesn’t bounce; they actually sit higher up on the chest than previous models, meaning you can sip on the move without bending your neck. Comes in men’s and women’s styles and sizes. JT


STRIIDE Athletic Sock

£11.99

Pro: Super soft and comfortable
Con: Only come in size 4-7

These retro looking socks from independent British fashion brand Striide Studio work really well for low-mileage jogs or a gym session with their targeted cushioning and supportive stay-put fit, while also being stylish enough to wear with everyday outfits. Made from a soft blend of 85% cotton, 13% polyester, and 2% spandex, they’re softer and more comfortable than standard nylon-heavy performance socks, but you might want a more technical and breathable fabric for long-distance runs. Although they only come in size 4-7, they’re super stretchy and felt comfortable on a size 8. If you’re looking for a multi-purpose sock that you can wear for working out or to run errands, these will be a good fit. JT


VUORI Long Sleeve Seamless Surge Tee

£85

Pro: Seamless design ensures zero chafing
Con: Size up if you prefer a loose laye
r
This running top works just as well as a technical item of clothing as a stylish top to wear anywhere. The seamless knit structure with zero side stitching means it doesn’t rub against your skin as you’re running or working out at the gym, even when sweating, while engineered mesh side panels are sewn directly into the knit fabric, helping you to stay much cooler than you’d imagine when wearing a long sleeve top. The fit is just right, not cropped but sitting right at the waist, which works well with running shorts. Choose your regular size for a comfortable form-fitting fit, or size up if you prefer a little more room. JT
