No problem. If you lack a runner, your team will be automatically assigned the time of the slowest runner. Likewise if you are missing a biker. Should a team be lacking an equestrian rider, the team will be assigned the same time as the equestrian who completes the course with the largest penalty time. We will use the same procedure if you are lacking two team members - unless, of course, you are competing as a soloist in all three disciplines.
