Interesting. I've never seen the benefit of upgrading to a watch with built in navigation function because the vast majority of my runs are road or track but I've dodged a few of my clubs virtual challenges during lockdown because I'd never ran the route before & there wasn't anyone else around my pace doing it.
I would heartily recommend it. Its added so much variation to my routes because it takes away the worry of getting lost. Takes a bit of tinkering setting up fields but it's pretty straightforward and for about 7 or 8 quid a year it's been a great purchase for me.
