Can I make a star shape?

My 45 minute 'jog' today was not as hard as I had imagined it would be. After a very good rest on Saturday, actually just reading a book all day, in bed (My back had gone into a painful mess on Friday so I decided not to run the next day)  I then managed 110 minutes Fartlek on Sunday trying not to go over the same route twice, which nearly worked.

So today's shape came out like this. And it occurs to me that I could make a star shape from it, with a little detour here and there.
