Family or PR?

I'm running the race with my younger sister. She is new to running and is slower than me, and I am torn.

I want to give it my all and see what I can do that day, but I don't want to hurt her feelings or discourage her from running in the future.

Anyone have any suggestions?

Either way, I think she would be pulling for you to do your best. I hate being the one slowing people down. Plus, as you know, there are plenty of other around that will be running the same pace as your sister.

I can't see her wanting to hold you up.

It's going to be pretty warm for you to try and go all out in this race. Might be better to hang with your sister and go for it in another race with better weather conditions. Think Chicago 2007. Good luck!
