Can I run with my child in a buggy?

No, I’m afraid it is not safe to run with a buggy.

How do I get my race pack?

If you opt to collect your race pack, you MUST collect it from the event village on Midsummer Common on the Saturday before the race. If you cannot get to the site before the day please opt to have your pack posted. There will be no race pack collection on the day, apart from overseas entrants.
Race packs will be sent, to those of you that have paid for postage, a couple of weeks before the event (we will give more precise dates once we know what they are). If you have not received your race pack 1 week before the event, please get in touch on 01522 699950.
It is your responsibility to check that we have the correct address for you. The details we have will be on your confirmation email. Please notify any changes as soon as possible to info@osbevents.com or by calling 01522 699950. Replacement packs issued due to incorrect information will need to be paid for.
If your circumstances have changed, and you would now like your pack posted, please call us by 5pm on Friday 17 September and we can add this for you. After this date we will be unable to post your pack to you and you will have to collect it from Midsummer Common on the day before the event. You will not be able to collect your pack on the day of the race.
If you are collecting your pack please remember to bring photo ID with you on the day as we will not be able to give you your race pack without it and we would hate for you to have a wasted trip.

Can I transfer my place?

You can transfer your place to someone else until 5 weeks before the event. The transfer must be completed by this date. You can make your transfer by logging in to your active account at www.active.com and clicking into My Events where you will see the button to transfer. There will also be a link on your confirmation email that you can use.
You will enter the email address of the person you are transferring to and then they will be sent an entry link. Once the other person has completed their entry, using the link that will be sent to them, you will be refunded your entry fee, minus the £10 transfer fee. Please note that Active processing fees are not refundable.
If the other athlete does not complete their entry before the 5 week deadline, you will not be refunded, and your place will stay live. If you are having difficulties, please call the office on 01522 699950 by the Friday before, as we will be unable to help you after.
If you have a charity or partner place, please note that these are not transferrable, and you will need to contact them directly to let them know that you cannot race.

I can’t find anyone to transfer my place to, can I withdraw and get a refund?

Have you tried the Cambridge Half Marathon Facebook page? There are always people looking for a place there. Running clubs are also a good place to find athletes wanting places.
You can withdraw until 5 weeks before the event to receive a partial refund. After this date there can be no refunds.
– Up to 84 days before the event you will receive your entry fee, minus a £10 cancellation fee.
– Between 83 and 42 days before the event the cancellation fee will be £15.
– Your last chance to withdraw will be 29 days before the event, when there will be a £20 cancellation fee.
– From 28 days before the event we cannot issue any refund.
If you need to withdraw please email info@osbevents.com as all withdrawals must be made in writing.

What time does the race start?

The race starts at 9:30, with a number of waves going off for almost an hour, therefore dependant on your estimated finish time, your start time could be much later. We will email you with your race number and wave time approximately three weeks before the race.

How do I get to the start?

For those that can walk or jog, please do as it will ease traffic congestion and is a great way to warm up. If you want to cycle, we will have a free secure bike park on site for up to 1,500 bikes.
For those travelling from further away please consider using our Event Buses, see the Bus Service Map HERE. This is a special event only service and must be booked in advance to guarantee availability. In 2021 we will again be using 6 sites, including St Ives & Longstanton, which both come in along the guided busway, alongside the sites at Milton, Trumpington, Newmarket and Madingley Road. For general site information please visit Cambridge Park and Ride and The Bus Way. Please note that tickets are per person NOT per car. Each person travelling needs a ticket for the bus service which we put on specially for the event.
Park & Ride can be booked when you enter or by visiting our shop from the front page.
Tickets are currently £6 per person but this will rise when we are not be able to send them in your race pack. Tickets can be ordered online until the Sunday one week before the event. After this date tickets will only be available at the site (If it hasn’t sold out) at an increased cost.
We also hope to have an event car park (Grafton West) which is within 200m of the event village.



Do you need volunteers?

Always! If you don’t fancy taking part yourself then volunteering is a great way to be part of the event and the amazing atmosphere! We always need amazing people to volunteer at our events, we literally couldn’t do it without you! All of our volunteers get food, a designated refreshment area, an event jacket and an exclusive gift.
We have a new system called Rosterfy which we are now using for volunteers. It will allow you to select your own job and will give you access to more information than before! Please follow the link on the volunteer page to sign up.
We are also always on the lookout for large groups to run feed stations and other areas that require a large number of volunteers, so if you are part of a running group, school, charity, knitting circle, sewing bee or just have a massive group of friends that would love to spend the day helping out, please get in touch with alan@osbevents.com and make his day!
