There are many benefits to trail running and everyone should do some, even if your main focus is road or track. The benefits are both mental and physical.
On the physical side, running off road will improve your balance, coordination, agility and strength. This comes through reacting to the varied terrain and tackling the hills. You may also find yourself out exercising for longer without noticing, if you find that mediative, flow state through focusing on the beauty of now and not the miles. It can really help to clear your mind, or find inspiration!
Trail running can take you to some amazing places. I’ve enjoyed epic races in Jordan, The Alps, Cornwall and the Peak District. You probably don’t even have to get that far from home to find yourself alone and in the quiet of nature. I’ve found myself not seeing a single other person along long stretches of footpath just outside Henley-on-Thames, Oxfordshire. Some people may find this a bit scary, but I love the peace and tranquility of moving through the landscape and being totally immersed in it. It is a far more immersive experience to run than walk trails. I think this is because you become totally focused on where you are going and how the terrain alters beneath your feet.

A final benefit that I found out about recently is that going out with a map (not GPS navigation) and getting lost are good to keep your brain active and working well. So get out there and explore!
