I'm assuming my bday will be spent at the house or with still pretty restrictive stuff going on.

I live in the Raleigh area and they also have my favorite gravel closed there, or that'd be what I'd do.

Any suggestions? I'm a cyclist, but my run volume is up to being able to run up to 10mi or so OK. Like at lower Z2 heartrate. I solo a metric century every week in around 3 hours.

Looking for something fun but challenging. Could be either, could be both.

I'd have to start and leave from my house in N Hills area.

So far I've got:

-created a hilly loop and go for 10k feet
-long duathon.........1/4 marathon, metric century, 1/4 marathon
-1/2 marathon to break 2 hrs (never done that, despite it being a rather slow pace for most)
-long ride only on a route I haven't done with maybe an interesting waypoint to see
-lazy metric century early AM and take a thermos of coffee and snacks (like a 4 hr metric instead of sub-3hr).

Other suggestions?
