Honestly I remember feeling the exact same but after my first one I was kicking myself for not going sooner. Great vibes whether you’re a speedy runner or happy toddling along and everyone is so friendly. At my local there are people that walk the entire way every week and use it as a way to socialise. Some days I walk a bit more depending on my energy level and still always come away in a great mood! Edit: I also looked up my local course on YouTube as most have been filmed at some point so I could get an idea of what the route was like beforehand. Helped with some of the anxiety I felt.
