Below is this week's segment – Cross Country Interference - Listen

I am running a great race at Michigan International Speedway. I’m about two miles into the 3.1-mile event, and I am on track to set a PR for the season.

As I run towards the next turn, a runner a few steps to my left, cuts right in front of me, causing me to slow down and nearly stumble. I regain my balance and keep going – but lose precious seconds during the altercation. Is interfering with a runner a penalty?

It is. If a race official sees a runner bump, trip, or run across another runner’s path causing them to change course or lose their natural rhythm, it’s interference. The runner charged with interference is disqualified. The runner who was interfered with continues on with his or her race.

Be the Referee: Illegal Substitution/Participation

Below is this week's segment – Illegal Substitution/Participation - Listen

We’re on the football field this week with 23 players.

Twenty-three is one too many; there should only be 22 on the field at once – 11 on offense, 11 on defense.

But on this play, the offense had a 12th player lined up on the field.

What’s the call?

It depends on when the penalty is spotted.

If the officials catch it before the play is run, that’s an illegal substitution and a 5-yard penalty.

But if the ball is snapped and a play is run with 12 on the field – and the 12th player is not attempting to get off the field – then it’s illegal participation and a 15-yard penalty. It’s also a 15-yard penalty if the offense uses a substitution to create a deception.
