After being selected in the Western States Endurance Run 100 (a cupless race) lottery for 2016, I purchased several of these cups (for myself as well as for my pacers/crew). They are made extremely well, and are lightweight and collapsible as advertised. A cup will easily fit in a pocket of my shorts or in my racing vest without taking up much space at all. I really look forward to practicing with them in the next few months then putting them through their paces at the end of June. Highly recommended.

Very nice product for keeping the race course of any distance a little cleaner. Plus no germ worries from pre filled cups sitting there.

no racer should be without their own personal cup! This C2Cup is great. Once you’ve used it swish it out with water and stuff it into your pocket ready for the next aid station. So much better than using a communal cup or adding to the heap of used cups heading for the landfill.

Love this cup!
Purchased 4, one for each of my running buddies and one for myself. Folds up small enough to fit in a zip pocket in my running shorts. No more wasting paper cups!

I use this cup for camping and hiking and it’s great! Fold it up, use it, swish it out, fold it up, done! Also great to have since no sharing allowed right now. 🙂

So I have to tell you how impressed people were with these cups this past weekend at Rocky Raccoon. I came into every AS with mine and asked for my soup/broth/mashed potatoes to be put in it. Every one of them said, “are you sure? It’s going to be really hot”. Every single one of them was astounded that they couldn’t feel the heat of the food that was inside it. Magical!!!!

With covid this past year I entered the rim to river 100 and it was a cup less race. I used this cup with ease because it can easily stand on its own which was nice to put down between sips and then super easy to stash in a small pocket for later use! Will continue to use even if cups are provided so I don’t have to worry about other cups or waste. Highly recommended!!!
I find these easy to keep clean. They store easy in a pack or pocket. If there is plenty of water at an aid station give it a quick rinse before moving on.

I love the C2 Cup! I have several of them and I use them during races. They are perfect for grabbing that quick drink of Coke at the aid stations. I have even used them for warm broth during cold weather events. I love the fact that these help reduce trash on the trails! These are great to have with a lot of events going cup less.

I love this cup!!! Used it for the past few years in every Ultra run. Compact, virtually weightless, and eliminates paper and styrofoam refuse in aid stations and on the trail. Also doubles as a shock and scratch resistant storage container for my headlamp, sunglasses or other loose goodies I may need to stash! Must have for any ultra!!

This is a great cup to use, probably the best I have tried as far as collapsible ones. It maintains its shape once it is open and will stand up when filled, but can scrunch down into a pocket really easily when you pack it away without poking out. I’ve used it in short trail races to multi-day ultras. I love not having to use wasteful disposable cups any more (and I know it’s just me using it, ha)

I ordered one of these for a cupless race I had in 2019. It was exactly what I needed. It weighs barely anything and collapses so you can toss it in a pack. Very durable and exactly what I needed! I was excited to see others using them at the Twisted Branch 100K.

First received my cup at the Bay Bridge Half Marathon. What a genius idea to reduce waste. More and More races should convert over. I have used this cup for many races since and don’t even bother with the paper products any longer at the aid stations. I am doing my part in reducing my carbon footprint.
Best hot/cold cup for going cup less. The ridges make it so much easier to hold than other brands and it still folds up just as tiny! Stay cup less!

The fastest, lightweight and most compact reusable cup I have ever used. I love how I can twist, bend and stuff it anywhere in my packs or belts.

I’ve had my C2 cup for a few years and love it. quite handy, extremely stash-able even in small pockets. Nice to use during cupless events, yet I use it at any race and like to see the delighted expression of aid station volunteers as they fill it to what ever level I desire. If you have ever had a pacer or crew help with events, these are perfect low cost cool gifts too.

Perfect do my cup free races! I love that I can just pull this out, fill up, drink and crush it down to nothing to put it back in a vest pocket. It takes up minimal room and is feather light. A must for ultra runners or anyone competing in a cupless race!
