This is the ultimate challenge and our most popular running event. If you'd like to be considered for a place and think you can raise £2,000 plus, download an application form, complete and return by Friday 4 November 2016.

If you already have a ballot place and would like to run for Rare Dementia Support, please email or phone 020 3448 3569.

If you'd prefer a different marathon or if running just isn't your thing, you can choose another challenge or find a place on your own and let us know.

Whatever you decide to do, choose National Brain Appeal as your charity and be sure to let us know that you are specifically fundraising for Rare Dementia Support.

For the third year running, Susie Shaw is organising a quiz that  spans continents and defies time-zones. Set your clock for 8pm GMT on Saturday 12 November and invite friends and family to join you then.

Email sgvq16@gmail.com to enter, and include details of all your team. Then donate a minimum of £10 per person here. Alternatively, text SGVQ61 £10 for each person registering in your team to 70070.

Following the passing of her mother, Myrtle Ellis, Susie and sister, Di Garfield, hope to make this the best year yet. Myrtle suffered with PCA for over a decate and was the inspiration for starting the Myrtle Ellis Fund, now incorporated into the fund for Rare Dementia Support.

Further details for how the quiz works can be found on the JustGiving donation page. Good luck!

Earlier this month, Jill Walton and Martin Jeeves took part in the Royal Parks Half Marathon in aid of Rare Dementia Support, and have raised almost £6,000 between them. In September, Chris Hardy took on the epic Iron Man Wales and swam, cycled and ran his way to over £3,800!

A huge thank you too if you supported them with donations - your generosity is much appreciated and helps maintain and extend the existing service for all those affected by an atypical dementia diagnosis.

We've had concerts, cake sales, coffee mornings, cookery demos and lots of runs as well as less usual events such as a trifle challenge and good hair colour day... and the year's not even finished yet! Keep up the good work, we look forward to hearing about more ideas, be they traditional or unusual.

Please encourage friends, family, colleagues and employers to support Rare Dementia Support by sharing the JustGiving campaign page: bit.ly/RDSfund

You can also link to this if you set up your own Justgiving page for a challenge or in memory of a loved one, and this ensures that all donations go directly to Rare Dementia Support.
