Classic Quarter - Cornwall UK

Hi, I’m looking for anyone who has run this and can share their experience. I’m not doing the Endurance Life race, but I plan to do the route in June while I’m staying in Cornwall for a few days.

I’ll be on my own, so I wondered:

Any bits where I might drop off a cliff or any risky climbing/scrambling sections?

Is the coastal path well signposted (I will have a map too)?

Anything else you think worth knowing about in advance!

Thanks v much.
