Queen Elizabeth Spring Marathon & Half
Run entirely on a half-marathon course within the Country Park (and the adjacent, aptly named 'Head Down' plantation) this is a trail run along well kept trails, that even after the long Winter should be nicely runnable. There are some hilly challenges that will take you on journey of over 500 metres of elevation gain over that half-marathon loop.
Once away from the busy front part of the Park, you will find yourself in the quiet peaceful forest, often with glimpses of wildlife. Later, on the last high point before you drop down to the finish area, there are long views through the clearings to the Solent and Isle of Wight.
