Collapsible race cups: the small kit for cup-free events

At a cup-free race, you want to reach the water station, take your cup out and use it without unpacking your vest. A collapsible cup gives you something to drink from at the checkpoint, then folds away for the next section. Choose one you can open easily and give it a permanent, reachable place in your kit.
I have used the Elovara collapsible cup clipped to my vest at checkpoints. The clip made it easy to find, and the lid helped keep dust off it between uses. I stopped to drink, emptied it and folded it away; that simple routine suited the job.

ToggleChoose for the checkpoint routine
Check the event instructions first: some races require a cup as part of the kit list, and you need to know how drinks will be provided. Think through receiving the drink, holding the filled cup and putting it away again. A cup that packs very small still needs a rim you can comfortably bring to your mouth.
The Elovara cup folds to a listed thickness of about 1.5cm and comes with a carabiner. That compact folded shape is useful where a rigid mug would take up too much room. Try opening the folds at home so you know when the cup is fully extended before it is filled.
Give it a place you can reach
Choose a front pocket or suitable attachment point that you can access with the vest on. If you clip the cup outside, check it stays out of your arm swing and does not tap against a bottle. Keep the attachment short and secure rather than leaving the cup dangling where it can catch.
A pocket can protect it from trail dirt, while a clip can make it easier to identify quickly. Try both with the rest of your normal load. I liked being able to find mine without rummaging, but the right spot depends on the pockets and attachment points on your own vest.
Practise with cold or gloved hands
- Retrieve the cup without pulling other items out with it.
- Remove the lid, if fitted, and keep it somewhere secure.
- Open the cup fully and hold it steadily for filling.
- Drink at the checkpoint, then empty any remainder where the event permits.
- Fold it, replace the lid and secure it before moving on.
A flexible cup needs a gentle grip: squeezing its sides when full can push the drink upwards. Try a small amount of water at home and learn how the rim feels. If you wear gloves, practise the lid and clip with those on too.

Keep the drinking rim clean
Store the cup away from used gel wrappers and muddy equipment. The lid on the Elovara is useful for covering it between stops. Check the rim before filling, particularly if the cup has been carried outside your pack.
After the event, wash it according to its care instructions, working around the folds and lid. Let all parts dry before folding it away for storage. A cup left damp at the bottom of a race bag is easy to forget until the next start line.
Plan water between the stations separately
A race cup makes drinking at a station convenient. Your plan for carrying water between stations still depends on the route, conditions and event provision. Do not rely on carrying a filled collapsible cup in a pocket as a substitute for a suitable closed bottle.
If you need both, give the cup and bottles separate places in your vest. Our flask-versus-bladder guide helps with the moving-water load, and the gel-carrying guide keeps food and sticky empties organised around it.
