Putting on a mass-participation event can put a strain not only on the organising team, but also the environment. Plastic bottles, tons of waste and thousands of miles of car journeys all add up to make even the smallest race a potential burden on the planet.

Thankfully, working to improve the environmental impact of your race can be simple, benefitting not only the environment but also your race’s image in the eyes of thousands of eco-conscious athletes.

We’ve put together some great tips to help you run a greener race, most of them at no additional cost to you. And here they are!

Water bottles/cups

Plastic bottles and cups are an environmental nightmare and, unfortunately, races the world over still go through a lot of them.

Fortunately, technology has come a long way over the recent years, and there’s now some very real alternatives available to help you reduce the environmental footprint of your waster stations.

Switch to more sustainable options

Instead of regular plastic cups, why not switch to biodegradable alternatives?

Biodegradable cups are made from bioplastics, such as PLA and other non-petroleum-based “plastics” made from biomass and other sustainable sources. Vegware are one of the pioneers in the use of plant-based packaging materials that often pops up in discussions around biodegradable cups in our race directors group.

Using biodegradable cups can have a huge impact on the environmental footprint of your race, with less CO2 being emitted and less water being used in the process. But you will still need to collect and properly compost all your event packaging, biodegradable or not.

Could your race make do without the plastic?

Go cupless

Even better, you can try to eliminate bottles and cups from your race altogether.

Sound radical?

It really isn’t. Many trail events already run cupless races, enforcing strict carry-your-own-container policies. With plenty of collapsible cup options now available in the market, such as HydraPak’s SpeedCup, UltrAspire’s C2 or NDURE’s Hydra, making your race cupless is easier than ever. And it may also help reduce your aid station crew’s workload.

For your cupless policy to work, you will still need to bring water in bulk to your water stations, but with products like WaterMonster you should be able to easily cover that angle. And if it’s something more than water you want to offer at aid stations, there’s any number of powder/tablet solutions you could try.


💡 How about offering branded eco cups to participants instead of the usual swag, such as T-shirts, medals and Buffs? NDURE offer this for their Hydra cup. It’s a really great, practical alternative to your usual giveaways and you can bet it will get a lot of use (and race exposure). And if giving them away sounds a bit generous, why not add some to your race merchandise line?


Go totally Ooho!

If you really want to go all out with your fight against waste, there are ways to not eliminate cups and bottles from your race, but eliminate the need for any sort of container altogether.

No, it doesn’t involve runners drinking out of troughs…But rather an ingenious new edible water container made out of seaweed. It’s called Ooho and it’s the coolest thing to hit races for some time.

If you’re thinking water containers made out of edible seaweed sound a bit far fetched, then think again. Ooho has been used to hydrate tens of thousands of participants with Lucozade during the 2019 Virgin London Marathon. And here’s how it all went down:



From what we hear from discussions in our race directors group, Skipping Rock Labs, the company behind Ooho are so inundated with requests from race directors to get Ooho in their races, that they are getting a bit overwhelmed. So don’t get disheartened if they’re slow to respond. Just think of all those amazed runners gulping seaweed pods in your next race. 🙂

Optional race goodies

Although most race participants would expect a nice technical tee as part of their entry fee, a lot of them will never wear it again after a race. That is a significant waste of resources that can be more cleverly redirected to everyone’s benefit.

Instead of receiving a technical goodie, why not ask your participants to opt – in advance – for a greener alternative? You can, for example, offer the option to contribute the cost of your giveaway item to charity or some environmental cause. You’ll be surprised how many participants choose to take this option and feel good about it too.

Reusing bibs

It may be a bit of a tricky manoeuvre to pull off in some of the more populous running races, but collecting bibs at the end of a race and reusing them could dramatically save down on race waste.

Reusing bib numbers could be easier in race series or team races, where people can register for a number of events and can be reasonably expected to try to reuse bibs throughout the series. If your race isn’t part of a series, it may still be worth to try to promote the reusable bib as an incentive in getting participants to return to the event.

Recycling bibs

If your race uses Tyvek bibs (and most races do) you can always try to collect and recycle the race bibs you issue to participants. Perhaps by asking them to hand them over as they receive their medals at the finishing chute or by placing collection bins around the finish area.

Normally, Tyvek is one of those tricky products that not all waste management facilities are equipped to handle. But if you’re based in the US and you’re really committed to giving bib recycling a go, you can always get in touch with DuPont’s recycling hotline on 1-800-44-TYVEK® or 1-800-448-9835, for more information on returning your unwanted race bibs.

Eco-friendly custom clothing

For those participants that do elect to receive a T-shirt, you can try to make it as environmentally friendly as possible.

Did you know you can produce a great quality technical T-shirt from recycled plastic bottles? Each shirt uses between 8 and 16 plastic bottles, depending on size and mix of other fibres such as recovered cotton. Now, there’s two birds with one eco stone for you!

Recover Brands’ bottles to T-shirt process

A number of companies offer printable tees from recycled plastics and other recovered or recycled materials. Here’s a few to get you started:

Another option to giving away technical tees is giving away cotton tees instead. Cotton T-shirts are a lot more versatile in real life and can be worn in more diverse occasions. If you decide to give out cotton, choose organic cotton, which is grown without pesticides and chemicals, for a greener choice.

Paperless communications

Sending and receiving paperwork is not only harmful to the environment, but also a logistical nightmare and a drag on valuable human resources. By digitising your registration forms, race manuals, medical certificates and other communications you can increase your efficiency while dramatically reducing paper waste.

To help you manage communications digitally, use services like Google Forms to create and share forms and cloud storage like Google Drive to share documents with your participants with the click of a button. If the use of paper forms is unavoidable, opt for recycled paper products wherever possible.

Virtual goodie bags

More to the point on paperless communications, should you really be delivering sponsor promotional materials in printed form? In a plastic goodie bag? That’s so 20th century….

How about opting for a virtual goodie bag instead? Your participants still get the same great offers, plus they’re always there and easy to find online without trees having to suffer in the process.

Want to have a go at putting together a basic virtual goodie bag yourself? All you’re going to need is:

  • A page on your website with all the offers
  • A link (or QR code, if you feel like going a bit fancier) to your page printed and handed over to your participants (or laminated, in a keyring, printed on their bib, the possibilities are endless!)

Eco-friendly race signs

If you’re planning to erect signs around your course, you may want to choose as eco-friendly a material as possible. Cardboard is usually a great choice for this, providing a good balance between durability when you need it and degradability when you don’t.

Like other initiatives on this list, carpooling can provide benefits to your event that go beyond the ecological. Getting your visitors and spectators to use a carpooling service will alleviate congestion around your course and foster a great community atmosphere around your race.

For smaller races, you can try to coordinate a carpooling service on a spreadsheet. However, the complexity of this quickly escalates with event size. If you want a bit of help, there are numerous dedicated carpooling software out there. Here’s a few:


Although we’ve focused the discussion so far on initiatives specific to mass-participation events, you can always aim to cover all the more common ways of cutting down on waste – such as reducing packaging.

If you are ordering medals, T-shirts or anything else, make sure you work with your supplier to minimise the amount of packaging used in shipping your supplies. For instance, ask your T-shirt printer to skip individual packaging for T-shirts. These are almost always non-recyclable and a shame to have to throw away.


If you’re running a large race and want to go the extra mile in making it environmentally sustainable, you could consider putting the effort in to make your event carbon-neutral. Making your event carbon-neutral ensures that your event has a zero net carbon footprint.

The way to making your event carbon-neutral begins with an assessment of your event’s carbon footprint. In this exercise, you will calculate the impact of your event on the environment in terms of carbon emissions. There are ways in which most activities like waste production, transportation etc can be reduced to a carbon-equivalent footprint.

Once your event’s carbon footprint has been calculated, you can work to reduce or offset contributions to it. You can reduce contributions by, for example, adopting initiatives like the ones discussed in this post. You can offset remaining contributions through carbon offsetting.
