So, it's a beautiful morning and the sun is shining. This would be a great time to have that relationship talk as you huff and puff up the hill on your cozy, tandem run. Right? So wrong. Nothing is going to irritate a dedicated runner more than a serious conversation during intense, focused exercise time. When your heart rates are high, attention should be placed on maintaining the pace and nothing more. Think of these as Zen moments, and keep the chat to a minimum. A heads up about a low-lying branch, broken glass in the path or the approach of a hungry looking dog is OK, otherwise, keep it short and sweet.
