Subject: Let's Go Running Together!

Hi Rob,

I hope you're doing well. I was thinking about going for a run this weekend, and it would be great if you could join me. How about running together on Saturday morning?

By the way, what time do you usually go running? Let me know so we can plan accordingly. I also know a really nice park nearby that’s perfect for a good run—I'm sure you’ll love it.

Looking forward to hearing from you!

Best,
