No, all ages are welcome!

The Marsden Mysteries is a self-guided team treasure hunt for all ages and is a brand new fundraising event from The Royal Marsden Cancer Charity.  


One week before the event you will be sent instructions to download the app, and a QR code for your game which is linked to your chosen start time. To begin your challenge, take a team selfie, give yourself a fun team name and you’re off! Using the interactive map and a live scoreboard your team will need to navigate via GPS to the right location to activate tasks, questions and challenges.

When is it?

Teams should expect to complete the challenge in 2-3 hours. You can go at your own pace and take a break whenever you need.

Where is it?

One fully-charged smartphone per team with mobile data and GPS enabled. Minimum operating systems required: Android Version 4.4 or iOS Version 9.0 (please see terms and conditions for recommended devices).

The route will start at a mystery location in the Kensington and Chelsea area of London. Exact details will be revealed approximately one week before the event.

It’s completely up to you, though as a guide we’d suggest a target of £300 per team. After you book we will send you some more details on how best to go about fundraising.  

What time does it start?

You can choose to take part on Saturday 30 September or Sunday 1 October 2017

There are a range of start times available on each day. Please select your chosen time when booking. There are limited places available for each start time.

Are there any age limits?
