So here's another two for one. My opinion on the above...have a long talk with your running "partner" before race day. Know what the other is expecting. You may be going for a PR and your partner may want to take it easy. Or what if one of you tweak your knee at mile 7. Now what? Just make sure each of you knows up front that there might be a possibility that you will have to split up. Or make a pact that you will stay together to the end. Whatever you decide, just do it BEFORE race day. Then all will be fine.
