Ultra Drop Bag Checklist: What to Pack for a Malaysian Trail Ultra
At a 100 km trail race you might see your drop bag twice in 20 hours. Whatever isn’t in it, you go without until the finish. Most drop bag mistakes aren’t missing big items. They are wet socks packed in an open bag, the wrong headlamp batteries, and food that looked good at home and now can’t be faced at 2am.
Here is what to pack, and how to split it.
How drop bags work
A drop bag is a bag you hand in before the race. The organiser carries it to one or more checkpoints along the course. Races differ a lot: some 50 km races have no drop bags at all, and 100 km races often have one or two. Check your race’s rules for the size limit, which checkpoints get bags, and whether you get the bag back at the finish.
The checklist
Feet
- A full change of socks, sealed in a zip bag
- Anti-chafe cream or tape
- A small towel to dry your feet before the new socks go on
- Spare shoes, for 100 km and above, a half size up if your feet swell
Fuel
- Gels or chews for the next section, counted out, not a handful
- Something savoury: crackers, a rice ball, salted nuts
- A calorie-dense backup for when aid station food runs out or stops appealing. A QC Stamina pouch is 260 kcal with 42 g carbohydrate and 13 g protein. You mix it with 150 to 200 ml of water, and a drop bag next to an aid station is exactly where you have both
- Your planned sodium for the next section, if your numbers call for it. Elec Stamina has 220 mg per caplet
- If you use Katsuo Stamina, the doses for the next section, counted in advance
Light and power
- A spare headlamp or fresh batteries, tested the night before
- Phone power bank and cable
Clothing
- A dry top, in a zip bag
- A light rain shell if you didn’t start with one
- A dry buff or cap
First aid and small things
- Blister plasters and tape
- Any personal medication
- Wet wipes and a few sheets of tissue
- A small bin bag to sit on or carry wet kit in
Splitting between two bags on a 100 km race
Pack each bag for the section that follows it, not for the whole race.
| Bag 1 (around halfway) | Bag 2 (around 70 to 80 km) | |
|---|---|---|
| Likely time of day | Late afternoon | Night |
| Priority | Dry feet, fuel reset, headlamp | Dry top (a warm layer for mountain races like Kinabalu or Cameron Highlands), savoury food, spare batteries |
| Fuel | Gels, savoury snack, 1 to 2 fuel pouches, sodium | Food you can still stomach when tired, 1 to 2 fuel pouches, sodium |
Packing tips that save time at the checkpoint
- Everything in labelled zip bags. Drop bags sit on wet ground and get rained on.
- Put the list on top. A card with what’s in the bag and what you plan to take out. Your brain stops working well after 12 hours.
- Pack in the order you’ll use it. Socks and towel on top, spares at the bottom.
- Set a time limit. Ten minutes at a drop bag is plenty. Sitting down for 40 costs more than any piece of kit saves.
- Pack spares you can leave behind. Don’t put anything in a drop bag you can’t afford to lose.
Before you pack a single gel, work out how much you’ll actually need for each section. For hot-weather race tactics, see Hot, Humid Trail Ultras in Malaysia, and for why protein belongs in the second half of a long race, read Protein During Ultramarathons.
