My hydration vest kit for a long cross-country course walk

A long cross-country course walk begins as a sensible inspection and can quietly turn into half a day on foot. There are fences to study, alternative routes to check, distances to judge and combinations to walk again because the first time I was thinking about the terrain instead of Archie’s stride. By the time I return to the float, I want water, shade and something savoury, not a heroic story about surviving on one mouthful from the car.

My hydration vest has become the easiest way to carry those essentials while keeping both hands free for a course map, phone or folded cap. It is lighter than a backpack, more practical than stuffing everything into breeches pockets and much less likely to be left beside a jump judge’s car. The contents change slightly with the venue and weather, but the basic system stays remarkably consistent.

Choosing a vest that works around horses

I use a running-style hydration vest rather than a traditional day pack. The close fit matters when I am climbing a bank, ducking under branches or moving briskly between fences. Loose straps swing around, catch on gate latches and become irritating within minutes. A vest with adjustable chest straps lets me wear it over a thin polo shirt in summer or a lightweight base layer on a cool morning.

Capacity is the first decision. For a short walk at a familiar local venue, a one- to two-litre bladder and a couple of pockets are enough. For a long course inspection at a big event, I prefer a vest with roughly five to eight litres of storage. I do not fill every compartment, because an overpacked vest becomes hot and uncomfortable, but I like having room for a rain shell, food and small safety items.

The fabric needs to cope with dust, sweat and the occasional encounter with a wet gate. Breathable mesh across the back is especially useful at events around Sydney or the hotter parts of Queensland, where the temperature can rise quickly after the morning briefing. I also look for secure zip pockets, a wide bladder opening and a drinking tube that can be clipped across the chest. If the tube bounces against my number bib or catches on a camera strap, I know about it very quickly.

Water comes before every other item

My main hydration supply is a two-litre reservoir. I fill it at home with cold water before leaving, then put it in the fridge overnight where possible. A reservoir is easier to drink from while walking than a bottle, and the weight sits close to my back. I take regular small sips rather than waiting until I am thirsty, particularly on exposed courses with little shade.

I also pack one soft flask as a backup. It can hold plain water, an electrolyte drink or water mixed with a powdered rehydration sachet. The spare bottle is useful if the venue has a drinking-water station but no convenient place to refill a bladder. Some Australian event grounds have taps near the stables or secretary’s office, while others involve a long walk back to the float, so I do not assume a refill will be available.

I am careful about hygiene. The reservoir is rinsed and dried properly after every event, with the tube left open to air. I have learned that a vest can smell unpleasant surprisingly quickly when a sugary sports drink is left inside it. I keep plain water in the bladder and carry electrolyte powder separately in a small sealed bag. That gives me control over the flavour and avoids turning the entire hydration system into a sticky science experiment.

Snacks that survive a long inspection

A course walk uses more energy than it appears to. At a large event, I may cover several kilometres over uneven ground, climb slopes repeatedly and spend time standing in full sun while discussing a fence with my coach. I carry food that can be eaten quickly and does not crumble into every pocket.

My reliable combination is a muesli bar, a banana or apple, and a small packet of salted crackers. The fruit is best eaten early because it bruises easily, while crackers remain useful later when I want something salty. I sometimes take a small peanut butter sandwich wrapped in paper, especially if the walk falls between breakfast and lunch. I avoid anything that melts, leaks or requires a spoon.

A few jelly lollies can be handy before a late section of the walk, but they are not a substitute for proper food or fluid. At Australian events, the canteen might offer a meat pie, sausage roll or coffee, but I do not rely on its opening time. Early course walks often happen before the first coffee van is ready, and rural venues can be a long drive from the nearest shop. A snack in the vest removes one small uncertainty from an already busy day.

Food also helps me judge my own concentration. If I become impatient at a related distance or start forgetting which route I have just walked, it may be time to eat, drink and sit under a tree for five minutes. Walking a course while tired can make every fence look more complicated than it is.

Sun, weather and the Australian landscape

Sunscreen is non-negotiable. I carry a small tube of broad-spectrum SPF 50+, even if I applied it before leaving the float. Australian UV can be high on a day that feels pleasantly cool, especially in Canberra or on a breezy Victorian course where the temperature disguises the strength of the sun. I also wear a cap with a brim and sunglasses with a retaining strap.

My vest contains a lightweight long-sleeved shirt or a thin windbreaker when the forecast is uncertain. Melbourne weather can change from bright sunshine to cold rain during a single course walk, while a venue outside Brisbane may feel humid and hot before breakfast. A packable rain shell weighs very little compared with the discomfort of being soaked while trying to think through a water complex.

I carry insect repellent in a small bottle, particularly for venues with long grass, dams or bush edges. Flies are a constant nuisance at some summer events, and in certain areas I also keep an eye out for ticks. A basic first-aid pouch contains a few plasters, blister pads, antiseptic wipes and an antihistamine. It is not intended to replace a proper medical kit at the event; it is for the ordinary problems that can make the walk miserable.

On courses beside bushland, I stay alert for uneven ground, loose rocks, fallen branches and snakes. I do not wander off marked paths to create a shortcut. Kangaroos are another reason to keep awareness up near dawn and dusk, when they may be moving across open ground. Sensible footwear, a charged phone and telling someone where I am heading matter more than carrying a huge collection of gadgets.

Maps, timing and course notes

The course map is folded into a clear waterproof sleeve or placed in a zip-lock bag. Even if I have downloaded the event app, I like a physical map that can be marked with a pencil. Phones lose signal, run out of battery or become difficult to read in bright light. The map also gives me something quick to show Archie’s groom or another rider when we are comparing routes.

I carry a small pencil, a permanent marker and a compact measuring wheel when the course and rules make detailed measuring worthwhile. Usually, I mark fence numbers, turning points, compulsory flags, water entries and the direction of related distances. I write brief notes rather than a paragraph at every obstacle: “open stride,” “hold line,” “watch landing,” or “alternative looks longer.”

A basic sports watch helps me estimate walking time and distance, although I do not treat its numbers as absolute. GPS can be unreliable around trees, hills and large crowds. The useful information is often comparative: this section takes longer than expected, the track between fences is deeply rutted, or the climb after the water will cost more energy than the map suggests.

I keep my phone in a zipped chest pocket, with the battery above half and the venue details saved offline. It is there for timing, photographs of tricky approaches and emergencies, not for scrolling while walking. Before heading out, I tell my coach or groom my intended route and make sure the sound is on. At a busy Australian event, it is easy to disappear behind a stand of trees or across the far side of a property.

Keeping the vest comfortable and useful

The most important packing habit is testing everything at home. I fill the bladder, put the food in its wrappers and walk around the block or along a local trail. That reveals rubbing, sloshing, noisy packaging and pockets that are impossible to open with one hand. A vest that feels perfect for ten minutes can become a problem after two hours.

I place heavy items close to my spine and low in the pack. The bladder sits against my back, while food and sunscreen go into front pockets for easy access. The rain shell is rolled into the top compartment. Small medical items stay together in a bright pouch, and the map remains flat rather than folded into a cramped corner. This arrangement means I can find something without emptying the entire vest onto damp grass.

I leave enough space to remove a layer and carry it. I also avoid hanging keys, loose camera straps or bulky radio equipment from the outside. Anything dangling can snag on a post, annoy another horse or become lost while I am concentrating on a fence. The cleaner the outside of the vest, the better.

Before the walk, I check that the drinking tube is clipped, the zips are closed and the bladder is not leaking. When I return, I note what I did not use and what I wished I had packed. My contents are different for a short schooling day at home than for a full event at Wagga Wagga or a sprawling property outside Melbourne, but the principles stay the same: carry enough fluid, protect against the weather, eat before concentration fades and keep the essentials reachable.

A hydration vest does not make the course walk effortless. It simply removes several avoidable distractions, leaving me more attention for the questions that matter: where Archie should land, how much pace the terrain will take from him and whether our chosen line still makes sense when viewed from the saddle.
