Today at my cross country race I ran an invitational which included many of the top runners from my county and group. Among the top runners I usually am a decent margin behind them. Today at the race I went out really hard with the top group and managed to stay with them for the first two miles. Once the last mile started I felt really good and pushed and ended up winning. At the finish line (with around 10 meters left) I pumped my fist by my chest. After the race when I checked to see the results and it ended up I got DQ for excessive celebration. Was it warranted?
