Runners on Embankment at the TCS London Marathon

Unable to take part?

Life doesn’t always go to plan and that’s why, for those who are eligible, we offer the opportunity to defer your place to next year’s TCS London Marathon.

The eligible entry types are outlined below, please read the criteria carefully.

If you are eligible, please submit your request via the Request Deferral button at the bottom of the page. This will take you through to Let's Do This where you will be asked to confirm your booking ID and details used to enter. Your booking ID can be found in the confirmation email received when you entered.

Please note, the deadline for requesting deferral is 23:59 on Saturday 20 April.

If you’re not eligible, no further action is required.

TCS London Marathon MyWay entries cannot be deferred.

Enhanced deferral options if you are pregnant or postpartum

If you are unable to take part because you are pregnant or postpartum, you can defer your place to one of the following three years. If you are pregnant or postpartum and hold a Good For Age* or Championship place, you can defer your entry to the same category as your original place without the need to qualify again. You’ll still need to pay the entry fee for the chosen year’s event to secure your deferred place and we’ll email you with details of how to do this.

* Please note that your Good For Age place will be in the appropriate age category for the newly-selected marathon.

UK entrants

Places via the ballot, running clubs and stakeholders

If you secure your place through the TCS London Marathon Ballot or have a guaranteed place from a running club or stakeholder (such as a local authority, emergency service, volunteer group or another group), you can defer your place to the TCS London Marathon the following year. You’ll still need to pay the entry fee for the following year's event to secure your deferred place and we’ll email you with details of how to do this.

Places provided by charities

If your place was provided by a charity, you cannot defer it via our system as the place belongs to the charity. Please contact the charity directly to discuss your options. Please note that the deferral of your place to a future year is at the charity’s discretion.
