We recommend that you allow two - three hours for the actual Treasure Hunt, with timings dependant on how competitive and fit you are, and how well you plan your route! These timings are given on the basis that all individuals within each team stick together throughout the hunt.
If the individuals within each team split up then you will complete the hunt in less than two hours so please ensure that all teams agree on the rules beforehand (this is explained in the ‘Rules & Procedures’ Handbook that goes out with your pack).
Conversely, you will probably spend more than three hours completing the hunt if you intend to have some refreshment stops along the way!
