Map convenience stores and small retailers into reliable pit stops for food, water, and toilets on multi-day walks or cycles.

Beat the uncertainty: map convenience stops so food, water and toilets never derail your long walk or cycle

Long routes are beautiful — until you’re low on water, your stomach is growling, or you can’t find a restroom. The pain: unclear availability, variable opening hours, and tedious multi-site planning. The solution: a resupply mapping system that turns convenience stores and small retailers into reliable pit stops along any multi-day, non‑motorized route.

Why this matters in 2026

Convenience retail expanded rapidly through late 2025. Large operators such as Asda Express have grown their footprint (surpassing 500 stores), making urban–rural corridor resupply far more common and predictable than five years ago. At the same time, mapping tech in 2026 — AI route planners, offline vector maps, and richer POI (point-of-interest) databases — makes precise resupply planning achievable from your phone and desktop.

"Convenience chains like Asda Express now offer over 500 locations, changing how long‑distance walkers and cyclists plan resupply stops." — Retail Gazette, January 2026 (industry milestone)

1. Build the route backbone — get the corridor right

Start with the exact line you’ll travel. For walking and cycling, small deviations matter.

Export your route GPX from your preferred planner (Komoot, RideWithGPS, Strava, or OS Maps).
Open the GPX in Google My Maps or an OSM-based tool (QGIS or the free UMap) to overlay POIs.
Create a buffer corridor of 500–1,000 metres for urban areas and 2–5 km for rural sections — this reflects the realistic detour distance for short resupply stops.

Why buffers matter

Detours in towns are short and often fast. Rural detours are longer; a 5 km detour for a store can add significant time, so only count stores inside the larger buffer when alternatives are limited.

2. Harvest store data: where to find reliable POIs

Good data is the backbone of a reliable plan. Pull POIs from multiple sources and reconcile them.

Google Maps / Google Business Profile: best for recent opening hours, photos, and real‑time busy times.
OpenStreetMap (OSM): excellent for small, independent retailers and rural stores often missed by Google.
Chain locators: Asda Express, Co-op, Spar, Tesco Express — use official locators to confirm addresses and trading hours.
Local council & tourism sites: public toilets and visitor centres.
Toilet and water apps: Flush, SitOrSquat, and UK-specific ToiletMap (2026 updates added more data points).

Tip: reconcile duplicates

Multiple sources will list the same store differently. Use address, phone number, and GPS coordinates to deduplicate. Export everything into a single CSV or My Maps layer for quick filtering.

3. Rank stops with a simple scoring model

Not all convenience stores are equal. Build a lightweight score to pick the best resupply stops.

Example score (0–10):

Accessibility (0–3): inside route buffer +1, on route +2, on main street +3
Hours (0–2): open 24/7 +2, extended hours +1, short hours 0
Facilities (0–2): public toilet or attached café +2, water refill available +1
Stock reliability (0–3): chain store +2, well-reviewed independent +1, unknown 0

Pick stops scoring 6+ as primary resupply points and 3–5 as backups.

4. Create a resupply cadence: how often should you stop?

Frequency depends on the trip profile. Use these simple rules:

Day hikes & light cycle tours: resupply every 20–30 km or every 3–6 hours.
Loaded multi-day tours: aim for 25–40 km resupply intervals or one major resupply per overnight segment.
Remote sections: extend to 60–90 km between resupply points but carry an emergency buffer (1–2 extra days’ food).

For water, plan to refill at least twice daily in moderate climates and 3–5 times in hot, dry conditions. Hydration needs range from 2–4 litres/day walking to 3–6+ litres/day cycling in heat.

5. Build the plan: step-by-step workflow

Import route GPX into Google My Maps or an offline-capable mapping app like OsmAnd or Gaia.
Overlay POIs from Google and OSM. Use different icons for convenience stores, cafés, public WCs, and water sources.
Apply scoring filter and highlight primary stops.
Create day-by-day resupply waypoints — label them with expected arrival windows and backup options.
Export a printable one‑page resupply table with km, ETA, store name, hours, and contact phone.
Download offline maps and cache the POI layers — crucial for rural gaps with poor signal.

Tool checklist (2026)

Google My Maps for desktop planning
OsmAnd / Maps.Me for offline routing and POIs
Komoot or RideWithGPS for detailed bike/walk routing
Google Sheets or Notion to consolidate store hours and phone numbers
What3Words or precise GPS coordinates for remote water points

6. Verify availability—don’t assume

Retail footprints have grown (Asda Express, Co-op convenience) but stores close or change hours. Always verify:

Check official chain locator (most accurate for store existence).
Look for recent Google Reviews or photos — fresh images indicate current operation.
Call if uncertain — a 30-second call can confirm opening hours and whether they sell hot food or accept card payments.
Social & local forums: X/Twitter, Facebook community groups, and local cycling/walking forums often report closures quickly in 2026.

7. Food planning: what to buy at convenience stops

Convenience stores are best for:

Carbs and quick energy: sandwiches, wraps, rice snacks, energy bars
Fresh snacks: fruit, yogurts, pre-cut salads (watch perishables)
Beverages: water, sports drinks, and hot drinks in cold weather
Fuel items: bread, cheese, tins for minimal cooking if staying overnight

Strategy: buy perishable items for the immediate segment and replenish dry goods at larger resupply points. For long remote sections, pre-plan one major shop at a supermarket or Asda Express-sized store before you leave civilisation.

8. Bathroom & hygiene strategy

Toilet access is a key comfort metric. Use a layered approach:

Cafés and pubs: often the most reliable toilets if you buy something.
Chain convenience stores: some have customer toilets or attached petrol stations with facilities.
Public WCs and visitor centres: usually shown on council maps and OSM.
Portable solutions: on very remote legs carry quick‑dry wipes, a small trowel, and a packit‑out bag if local rules require.

9. Special considerations for cycle tours (2026)

Cycle touring benefits from speed but loses flexibility if you carry panniers. Account for:

Bike parking & security: choose stops with visible parking or secure racks.
E‑bike charging: identify café or supermarket with 13A sockets or EV chargers adapted for e-bike use (growing trend in 2026) — see our value comparison for rider tech for charger options.
Mechanic access: flag bike shops or general repair points along your route — consider mobile fitment and micro-service vans in remote sections.
Food weight: buy high‑calorie, compact foods to maintain pace.

10. Risk management: backups and emergency buffers

Even the best plan needs redundancy. Add buffers to avoid being stuck.

Carry a 12–24 hour food buffer for unexpected closures or bad weather.
Extra water: at least 1 litre of emergency water beyond expected refills.
Phone & power: power bank charged; note places with reliable charging (supermarkets and larger convenience stores often have public USB points in 2026).
Alternate transport: list nearest public transport stops (bus/train) for evacuation if needed.

11. Case study: mapping a 120 km multi-day route

Here’s a condensed practical example you can replicate. Route: a 3‑day point‑to‑point walk/cycle covering 120 km with mixed urban and rural sections.

Day 0 prep

Export GPX from Komoot and import into Google My Maps.
Apply a 2 km rural / 500 m urban buffer.
Pull POIs: Asda Express (2 locations), two Co‑op stores, three independents, two pubs with all‑day service, and five public water/toilet stops.

Day breakdown

Day 1 (40 km): Resupply at a town 18 km in (Asda Express) — buy full-day perishables and hydrate. Backup: village shop at 11 km.
Day 2 (45 km): Early café + town supermarket in mid-section for hot food, and a 24/7 express store at 32 km for evening snacks. Water refill at two public fountains mapped with What3Words coordinates.
Day 3 (35 km): Smaller rural stretch — start with full water and high-calorie dry goods from previous night’s shop; final resupply in endpoint town.

Each primary stop had one backup within the buffer and a 12‑hour food buffer carried. The plan included offline maps and printed waypoint table with phone numbers and opening hours.

12. 2026 trends that change resupply planning

Convenience store expansion: chains have increased micro‑stores near commuter corridors; Asda Express reaching 500+ outlets means more predictable mid-route options.
Micro-fulfilment & click-and-collect: same-day store pickups let you pre-order at a chain on the morning of arrival for guaranteed stock.
Offline AI planners: route planners can now auto-suggest resupply points and generate printable shopping lists based on daily calorie targets.
Refill stations and sustainability: more stores offer water refills and packaging‑free snacks — good for lightweight touring.

13. On-the-ground verification checklist

Before you commit to a store for resupply:

Confirm hours (call or check Google Business updated hours)
Note card vs cash acceptance (contactless is widespread in 2026, but some independents prefer cash)
Identify toilet access policy (customer-only or public)
Check for secure bike parking if cycling

14. Advanced tips for route pros

Automated alerts: set Google Alerts or X/Twitter search for store name + "closed" or "temporary" for long lead times.
Shared resupply layer: publish a public My Maps layer for community feedback — locals will often flag temporary closures or route hazards. Consider community-facing micro-experience and pop-up guides like those in micro-experience playbooks.
Preorder & pickup: use chain click-and-collect where available — saves weight and guarantees stock.
Leverage local businesses: call independent cafés to arrange a late open or a reserved packet for a group ride.

Final checklist before you go

GPX route exported and offline maps downloaded
Primary and backup resupply stops mapped and scored
Printed one‑page resupply table with contacts and opening hours
Food, water and emergency buffers packed
Power bank, basic repair kit (for cycles), and a compact hygiene kit

Wrap-up: make resupply planning part of the adventure

Smart resupply mapping removes stress and keeps your focus on the trail and the ride. In 2026, more convenience options and smarter mapping tech make it easier than ever to convert small retail outlets into reliable checkpoints. Use the workflows above to build resilient plans, verify availability before you leave, and keep a safety buffer.

Actionable takeaway: export your route, overlay POIs from Google and OSM, score each stop, and print a one‑page resupply table. If you’re planning a specific route, pre‑order at an Asda Express or similar store the morning of arrival for guaranteed stock.
