There are two ways you can apply to run for us.

Our cheer squad support will motivate you as you tackle the 26.2 miles on the day!

Please submit an application with as much detail as you can, including why you want to run for the Haemophilia Society and how you plan to reach your fundraising target. We will be allocating places from September.

    Terms and Conditions

    Please read carefully

    Thank you for considering taking part in the London Marathon to raise money for the Haemophilia Society (THS). THS has a limited number of Golden Bond places for this event. If your application is successful, you pledge to run the London Marathon 2026 and raise at least £2500 for THS through JustGiving, linking to the THS JustGiving campaign page. I understand that the minimum fundraising pledge of £2500 to be raised for THS applies per person. Your application will be subject to a selection process so that THS can ensure that Golden Bond places are used to best-possible effect.

    If offered a THS charity place, you agree to wear the THS branded running t-shirt or vest while participating in the London Marathon.

    THS does not take responsibility for any health issues during your training for the London Marathon or any incidents that occur on race day. If you have any health concerns prior to, or during, your training please consult with your doctor/physio.

    THS reserves the right to refuse an application at its absolute discretion.

    You must be 18 years or over on the day of the race.

    If you are unable to participate in the event for any reason, all donated monies collected in support of THS must be forwarded to the charity or returned to the individual sponsors. Monies already received by the charity will not be refunded.

    If you wish to withdraw for any reason after the official registration has closed, please contact THS before the day of the run. It is important that you do not take part in the marathon unless you are completely fit to do so. If you wish to defer your place to the following year, please make THS aware as soon as possible so that a decision can be made and a place reserved for you if available.

    When THS establishes contact described as "urgent", runners must respond via email/telephone/in writing as quickly as possible.

    By signing up to London Marathon you are consenting to THS using any images taken on the day of the Marathon in our promotional materials. Please contact us in advance of the event if you are unhappy with this arrangement.

    I have read and understood the terms and conditions above and would like to apply for a THS Golden Bond place. I acknowledge that, upon acceptance, I am undertaking a pledge to raise £2500 for THS by the day of the London Marathon.

    Claim Gift Aid

    N.B. You must pay an amount of income tax or capital gains tax equal to the tax we reclaim on your donations (currently 25p for every £1 you give). Please let us know if your circumstances or address details change so that we can update our records.
