Level 2 runs are a mixture of flat and undulating sections on runnable terrain.

Our difficulty level reflects the amount of elevation you will encounter on the route and a measure of how tough/technical the terrain is.

Please note: This itinerary assumes you are travelling via train from central London however we welcome runners from anywhere!

If you're driving, see below for parking details.

Meeting points


There will be no meeting point in order to minimise social contact. Please board the train on our own or in small groups.

Route start

Meet outside the main entrance of Great Missenden station. The guides will be there from 09:50.

Please meet the Runaway team at the meeting point 15-20mins prior to departure.

There is plenty of parking at Great Missenden station.

If pubs have reopened we will aim to have some post-run drinks in a local pub beer garden.

It's unlikely we will be able to have a group lunch together, so please arrange this yourself or bring some post run snacks.

If we can reserve an area we will, however we don’t formally book a table as this often requires a deposit/exact numbers. If the chosen pub/cafe is full or busy we will try somewhere else.
