Cross country races are won in July, not October. The aerobic engine you race on in the fall is built during the unglamorous summer weeks of consistent, progressive mileage. The work that happens with no meets, no crowds, and no one watching.

That's exactly why summer is so easy to waste. Without structure, most runners either do too little (a few jogs a week, no progression) or too much too soon (jumping mileage, getting hurt by July). Both roads lead to the same place: a flat, frustrating fall season.
