Our amazing volunteers are essential to the success of this fantastic event.  Volunteering is a great way to enjoy the race atmosphere while supporting thousands of runners to achieve their goals and raise more than £500k for charity.  We would love to have you join the team!

We offer a wide range of roles and shifts across the event weekend, so there is something to suit everyone.  We ensure you receive the training you need and on the day you will be supported by our team of friendly and experienced crew members.

We really appreciate you giving your time and energy.  As a thank you, we offer our volunteers:

• Cambridge Half Marathon Volunteer Jacket
• Cambridge Half Marathon Volunteer Gift
• Event Goody Bag
• Food, drink and snacks
• A dedicated rest area on Midsummer Common
• Park & Ride tickets for our special race day service
• Access to a guaranteed entry to the 2023 TTP Cambridge Half Marathon


We have hundreds of volunteers working together to make this event a success, so we use a system called Rosterfy to co-ordinate everyone and ensure you receive the information you need.  If you would like to volunteer, please:

1. Log into or create a Rosterfy Account with OSB Events
2. Apply for the Cambridge Half Marathon 2022 Event and complete the Expression of Interest form
3. Once registered for the event, you can select which shift you would like to do

Which days do you need volunteers?

Sunday is the biggest day where we require the biggest team however we also need help on Friday and Saturday, helping runners collect their pack and preparing everything for race day.

What roles are available?

Course Marshalls – a great way to see the race in action, you will be helping to direct and support runners and spectators around the 13.1 mile course. Pick a role in one of our Race Zones (A-K) or on one of the locations on the course.
Start / Finish Line team – based around Midsummer Common, this role gives an opportunity to encourage runners as they set off and congratulate them when they finish. You could be helping to organise people at the start, giving them their medals and goody bags at the end.
Park and Ride team – be part of the team that helps to settle nerves and boost confidence as runners make their way to Midsummer Common. You will be helping get everyone off their bus and directing them to the event site. These shifts start and finish early so you can also join another shift after e.g. Finish team
Enquiries & Pack Collection – a job for Friday and Saturday, you will be helping to reduce runners stress by ensuring they have everything they need before the race starts. You will be on hand to match runners to their race packs as well as help with general queries about the event.
Volunteers – look after the people who look after our athletes. You will be helping everyone to be in the right place at the right time with the right stuff (as well as ensuring everyone can get a cup of tea and a biscuit!)
Merchandise – Runners love a race memento to remind them of their big achievement. You will be helping people to pick and buy their hoodies, t-shirts and vests.
Set Up Team – if you’ve ever wondered what goes on behind the scenes to host a race for 15,000 runners, join the Set Up Team on Friday and Saturday. You will get involved in the wide variety of tasks required to prepare and organise before the big day.

I’m part of a group – can we volunteer together as a team?

Yes, we often work with clubs and community groups. Please email us at Volunteers@osbevents.com with contact details and we will be in touch.

Can my friend and I volunteer together?

We can’t guarantee that you will be able to work next to your friend for the entire shift as we will always need to move people around to meet demand. However if you both select the same shift (look for ones with multiple positions available) you are very likely to be working together and will be able to arrive and leave together.

Will I receive training?

We ensure everyone receives the information, training and equipment required for their selected shift. We produce a video briefing in advance of the race as well as sharing written information where appropriate. On the day, you will also be supported by your Team Leader, one of our regular Crew members who will provide a briefing and be on hand for any questions and issues which arise.

How do I get to my meeting point?

For every shift, we will provide you with details of where you need to be and by when (you will find these details in your Rosterfy account by clicking the ‘information’ tab) You will need to make your own arrangements for travel for all roles, whether on Midsummer Common or out on the Course.
We do offer volunteers on race day the option to use our special Park and Ride service for free – to receive these tickets, you must sign up by Sunday 27th February. More information about this service is on the Event Information page. Please note – this service is ticketed per user not per car, so if you have friends and family coming with you who are not volunteering, they will need to purchase their own tickets.

How will I receive my 2023 Race Entry Link?

These will be sent out to those who request them as the 2023 event opens for sales, towards the end of 2022. Please note, it gives you access to a guaranteed place in this extremely popular event but entry fees will still apply.
