Why your pack matters more than your pace

A run in the Highlands is a different animal from a loop of the local park. Within twenty minutes of leaving the car you can be on open moorland with no shelter, no phone signal and a wind that arrived from nowhere. Weather here turns fast — a bright morning can close in to horizontal rain and clag before lunch — and the ground underfoot shifts from springy deer grass to wet rock to loose scree without warning.

None of that should put you off. It simply means that a little thought put into your pack before you set off buys you an enormous amount of freedom once you're out there. The aim isn't to carry a small removal van on your back. A well-chosen 10 to 15 litre running vest, packed with intent, weighs barely more than a full water bottle and disappears once you're moving.

The five things you never leave behind

If you remember nothing else from this article, remember this list. It forms the core of any hill day, whether you're jogging a forestry track at Aberfoyle or eyeing a long ridge in Torridon.

• Map — a paper map of the area you're actually running, kept in a clear case or laminated. Batteries fail, screens crack and cold fingers fumble; paper doesn't. Know how to read it, and know your escape routes.
• Compass — a baseplate compass weighs almost nothing and works when everything else has given up. If you can't yet take a bearing and follow it, that's a skill worth a short course or an evening with a friend who can.
• Whistle — the international distress signal is six blasts, pause, repeat. It carries far further than a shout and costs you no breath. Keep it on a cord around your neck or clipped where you can reach it with cold hands.
• Waterproof jacket — not a showerproof smock. Look for taped seams, a proper hood and enough room to wear it over a mid-layer. Even in July, an unplanned hour in wet wind can chill you quickly.
• Water — enough for the route you've planned, plus a margin. There are plenty of burns, but treating water takes time and kit, so carry what you need rather than assuming you'll find it.

Layers, because the weather will change

Dress for the forecast but pack for the worst hour of it. A thin fleece or insulated mid-layer, a lightweight hat and gloves, and a spare buff take up very little space and make the difference between a memorable run and a miserable one. Even on a warm day, the temperature on an exposed ridge can sit several degrees below the glen, and wind chill does the rest.

Waterproof trousers are worth considering for longer or more exposed routes. They're the piece of kit people most often leave behind and most often wish they hadn't, particularly on a long descent in driving rain when your legs are already tired.

Water, food and fuel for the hills

Hill running burns more than you expect, and bonking on a remote track is both unpleasant and avoidable. Carry more food than you think you need: a couple of energy bars, some dried fruit, a sandwich, a handful of sweets. Things that don't freeze solid or turn to crumbs in the bottom of your pack are the winners.

• Roughly 500ml of water per hour of running in cool conditions, more in heat or on steep ground.
• Aim to eat something small every 45 to 60 minutes rather than waiting until you feel empty.
• Add a spare gel or bar for the "just in case" moments — a wrong turn, a slower group member, a route that takes longer than planned.

The small kit that earns its place

Beyond the essentials, these items sit at the bottom of the pack for months without being touched and then save the day. A lightweight foil blanket, a head torch with fresh batteries, a small first aid kit with blister plasters and tape, a few metres of cord, and a phone in a waterproof pouch. A printed card with your emergency contact details and any medical information is a small, sensible addition — particularly if you run alone.

If you're heading somewhere genuinely remote, consider a personal locator beacon. It's a real investment, but for regular solo days in the far north-west it's the kind of insurance you hope never to use.

Telling someone where you are going

This is the cheapest safety measure there is and the one most often skipped. Before you leave, tell someone your planned route, your expected finish time and what to do if you're not back. Give them the grid references for your start and finish, and a rough line of travel between them. Then agree a time to check in — a text from the car park is enough.

If your plans change, tell them. If you're running with a group, make sure at least one person knows the route and holds the map. And if you do end up overdue, that call to the emergency services becomes far quicker and far more effective when someone can say exactly where you should be and when you were due. Pack well, plan well, and the hills stay open to you in every season.
