Sounds like me running from Delacombe to go for a nice run around the lake only to find when you get there you have to turn around and run home
If you stick to the higher paths it may be more worthwhile, but not quite as nice (and more chance of bunping into the local cottaging scene at bummer's bend...)
Haha yeah Rivelin is so nice, it's worth it for a 75 minute run but 60 is too short. Good thing you have much more interesting runs than Delacombe -> Lake now! Though at least it went through Vicky Park.
The top paths are pretty nice but yeah not quite the same. You get a good view over the valley on a nice day. Haha I have never heard of bummer's bend, or come across them before! Interesting...
