That’s a good incentive to run, a bit too away for me. Something other sites could take up to!
Goodness, if I lived close enough I might even be tempted to do a quick totter just to get into the Eden Project for free!
If you are a parkrunner (and you don’t have to run to be a parkrunner!), try the parkrun at the Eden Project in Cornwall. If you do the run, which is completely free, you get free entry into Eden Project which normally costs over £20!
