Stage races reward runners who can repeat a good day. Your packing list should make that possible: move efficiently during the stage, recover quickly afterward, and wake up with everything ready to do it again.
The Two-Bag System
Most stage race gear falls into two systems: what you carry while running, and what you use between stages. Some races are self-supported, which means those systems collapse into one pack. Others transport a camp bag or allow drop bags.
Daily Carry
| Category | Pack | Decision Basis |
|---|---|---|
| Hydration | Required capacity in a practiced bottle or bladder system | Race minimums, weather, aid spacing, and individual plan |
| Weather | Exact mandatory layers plus tested condition-specific options | Forecast, exposure, altitude, and organizer updates |
| Safety | Every required emergency, navigation, and tracking item | Carry and use each item exactly as the rules specify |
| Food | Required minimum plus personally tested, permitted options | Event provision, allergies, tolerance, and individual plan |
| Feet | Permitted supplies you have tested and know how to use | Pause safely to inspect symptoms; seek event medical help as needed |
A Worked Self-Supported Pack, Item by Item
The list below is an illustrative build for a seven-day, self-supported desert race, built around the compulsory items in Article 21 of the Marathon des Sables 2027 regulations. MdS publishes two hard numbers that set the shape of the whole pack: competitors must carry at least 2,000 kcal of food per race day during the timed stages, which the 2027 event page totals at 12,000 kcal for its six stages, and the pack plus personal belongings must weigh between 6.5 kg and 15 kg, excluding the daily water supply. The 2027 rules also set a 400-lumen minimum for the head torch, which must come with a full set of spare batteries or a spare battery with an external or solar charger, and the organizers provide no charging. Weigh your own items: only the pack weight and the two light weights below are manufacturer figures, and everything else is a realistic placeholder you should replace on a kitchen scale.
| Item | Weight | Note |
|---|---|---|
| Pack (WAA MDS Ultra Bag 20 L) | 640 g | Manufacturer figure, without accessories; 870 g with |
| Sleeping bag | 450 g | Compulsory; illustrative |
| Closed-cell mat, trimmed | 150 g | Not compulsory; illustrative |
| Head torch (Petzl NAO RL) | 145 g | Compulsory, 400 lumens minimum; manufacturer figure (1,500 lumens maximum) |
| Spare battery for head torch | 85 g | Compulsory ("with spare batteries"); illustrative |
| Backup light (Nitecore NU25 MCT UL) | 47 g | Not compulsory; manufacturer figure from our headlamp guide |
| Compass, 1° or 2° precision | 30 g | Compulsory; illustrative |
| Knife with metal blade | 25 g | Compulsory; illustrative |
| Lighter | 11 g | Compulsory; illustrative |
| 10 safety pins | 5 g | Compulsory; illustrative |
| Signalling mirror | 15 g | Compulsory; illustrative |
| Aluminium survival sheet | 60 g | Compulsory; illustrative |
| Topical disinfectant | 30 g | Compulsory; illustrative |
| Sun cream tube, 50 ml minimum | 60 g | Compulsory; illustrative |
| Sunglasses | 30 g | Compulsory; illustrative |
| Stock cubes, 14 (2 per race day) | 140 g | Compulsory; illustrative at 10 g a cube |
| Whistle | 0 g | Compulsory; integrated in this pack, so no added weight |
| Passport, medical certificate, ECG, €200 cash | 80 g | Compulsory; illustrative |
| Compulsory and safety subtotal | 2,003 g | Sum of the rows above |
| Stove: solid-fuel tabs, titanium pot, stand | 180 g | Gas stoves are prohibited at MdS; illustrative |
| Spork | 10 g | Illustrative |
| Foot-care kit: tape, scissors, needle, wipes, lube | 150 g | Illustrative |
| 2 spare pairs of socks | 90 g | Illustrative |
| Long-sleeve sun layer | 120 g | Illustrative |
| Sleep base layer and spare shorts | 200 g | Illustrative |
| Toilet tissue, wipes, hand gel, 7 days | 120 g | Illustrative |
| Electrolyte tablets, 7 days | 60 g | Illustrative |
| Power bank and cable | 130 g | Illustrative |
| Dry bags and ziplocks | 60 g | Illustrative |
| Personal-kit subtotal | 1,120 g | Sum of the rows above |
| Food, 7 days | 3,850 g | See the food plan below |
| Pack total at the start | 6,973 g (6.97 kg) | 2,003 + 1,120 + 3,850; inside the 6.5–15 kg window |
Two things about that total. First, it sits only 473 g above the 6.5 kg minimum, so on this build the risk is failing the lower bound after a couple of days of eating, not the upper one — MdS weighs packs at registration, but a very light build is also a build with no margin for a forgotten item. Second, it excludes water: the daily supply is carried on top, and 1.5 L adds another 1,500 g at each stage start.
Meeting the Calorie Minimum
The MdS 2027 regulations require at least 2,000 kcal per race day, and the 2027 event page puts the total at 12,000 kcal. RacingThePlanet's 4 Deserts races require 14,000 kcal for seven days. The example day below reaches 2,110 kcal in 550 g, an average of 3.84 kcal per gram. Two of the three lines use a published product figure; the third states its assumed density.
| Item | Dry weight | Energy | Source of the figure |
|---|---|---|---|
| Breakfast: dehydrated meal, XL | 200 g | 755 kcal | Firepot published figure (200 g dry, 755 kcal) |
| In-stage: bars, gels and drink mix | 150 g | 600 kcal | Assumed 4.0 kcal/g |
| Dinner: dehydrated meal, XL | 200 g | 755 kcal | Firepot published figure |
| Day total | 550 g | 2,110 kcal | Sum of the rows above |
| Seven days | 3,850 g | 14,770 kcal | 550 × 7 and 2,110 × 7 |
14,770 kcal clears RacingThePlanet's 14,000 kcal by 770 kcal and the MdS 12,000 kcal total by 2,770 kcal, and 2,110 kcal per day clears the daily minimum by 110 kcal. That is a deliberately thin margin on the day figure: MdS checks food at its technical checks, falling under 2,000 kcal per race day costs a 2-hour penalty and can mean disqualification, and a pack that loses one meal to a split bag no longer complies. Adding one more 200 g XL meal for the week costs 200 g and buys 755 kcal of headroom.
The calorie minimum is a compliance rule, not an intake recommendation. Multi-day desert stages routinely cost far more than 2,000 kcal a day, so the pack is a compromise between the energy you would ideally eat and the weight you have to carry it in. Food not in its original packaging must carry legible nutritional labelling; keep the labels you cut off.
RacingThePlanet's 4 Deserts events use a similar structure — 35 mandatory items and a "minimum of 14,000 calories for the full 7 days" — but differ in detail: a 150+ lumen headlamp is specified, three pairs of socks are required rather than recommended, and a 2.5 L water capacity is mandated. Never carry one race's list to another race.
Older MdS lists still circulate. The undated MdS UK compulsory-kit page lists an anti-venom pump and "14,000 k/calories"; neither appears in the 2027 regulations, which list no pump and set the food rule per race day. When two MdS lists disagree, follow the regulations for your edition.
Camp or Transfer Bag
If the race transports a bag, adapt it to the services, bag limits, and conditions described in the manual. Depending on the event, useful categories can include dry clothing, sleep gear, food, foot care, charging, and simple hygiene. Organize priority items so they are easy to find after a stage.
- Dry shirt, warm layer, camp shoes, and sleep socks.
- Recovery food you can eat even when tired.
- Full foot-care kit with tape, pads, scissors, towel, and lube.
- Charging cables, power bank, and labeled electronics pouch.
- Small repair items: safety pins, tape, spare bottle cap, zip bag.
Food and Fuel
Food rules and availability differ sharply between supported and self-supported events. Meet the organizer's minimums, then choose foods around allergies, medical needs, storage conditions, and what you have tolerated in comparable training. Weight efficiency can matter in a self-supported race, but it should not replace an individualized plan.
For hydration planning, read Hydration and Sodium for Ultramarathons.
Foot Care
Inspect feet when discomfort appears and after a stage when practical. Cleaning, drying, sock changes, and a tested friction strategy may help when conditions call for them. New or worsening pain, numbness, marked swelling, broken skin, or an altered gait needs assessment rather than another layer of tape; use event medical staff when available.
Use the foot care kit guide to build a compact race version and a fuller camp version.
Packing Mistakes
- Testing shoes but not testing the shoes with the loaded pack.
- Carrying too many food options during the stage and none at camp.
- Forgetting that wet wipes, sunscreen, and lube can leak.
- Using one giant bag instead of small labeled bags.
- Ignoring the race manual because another race had different rules.

Frequently Asked Questions
What is the most important stage race gear?
The current race manual decides the non-negotiable gear. Beyond that, prioritize a tested pack and footwear, required water capacity, weather protection, navigation and emergency items, and any personal medical supplies permitted by the organizer.
Should you pack different shoes for a stage race?
Only if the rules and transport setup allow it and a separately tested pair addresses a likely surface, weather, or fit need. There is no default requirement for a larger shoe; excess space can also create movement and friction.
How should you organize a stage race bag?
Organize by daily routine: start-line kit, in-stage fuel, finish-line recovery, foot care, sleep, and weather protection. Small labeled dry bags reduce mistakes when tired.
