Can you explain the lockdown rules and what area you're in? In the UK I'm now in the highest risk area and still allowed to walk and cycle from home and travel around my county by car. That could easily be a 20 mile walk or 50 mile bike ride from home if I had time on my hands. I could take a mask and buy takeaway food from a shop or cafe. Just trying to compare the rules in different areas.

Harshest lockdown in the UK was probably in Scotland where you were restricted to not be more than 5 miles home which could still easily allow a 10 mile walk.
