Jogging w/baby

I go running wiht my daughter who is 1.5 years old. She is in her size 2-3 clothes(big girl lol). I have an urban detour jogging stroller, and she still fits quite comfortbly in it. The only issues I have is:
1. she is heavy and it gets tiring to push her
2. She gets bored after about an hour of running
3. my stride changes drastically when I run with my jogging stoller

I would rather run with her however, than not be able to run at all And she enjoys our time outside as well!
