15 Finish Setup of start and finish Well marked finish lanes (flags, tassels) At least 4 lanes of 3 m (10 feet) each Lanes even/equal across (use forerunners?) Well marked start of finish zone (skier can not switch lanes inside zone unless overtaking) Finish photo/video camera If tie, best qualification time advances/wins

16 Courses Sprint Courses From km (3 minute race optimal?) Should include some straight uphills Should avoid sharp corners in critical points (start or before finish) Corners should be fenced/v-boarded (to avoid short-cuts)

17 Courses Sprint Courses Close course before start? Can use marked corridors somewhere on course skiers must stay in marked corridors must be on straight sections => makes overtaking easier Finish stretch should not be downhill Finish zone should be at at least 100 m straight Course should be in view from stadium - and with video/vcr available (planning!)

20 How to Organize a Sprint Important elements: Qualification: Needed at all (16 or 24 competitors in class)? start interval (15, 20 or 30 sec)? start order (goal to limit overtaking) Draw for best seed, by points for others information to qualifiers (as soon as possible) length of break before final heats? Plan for bib handout after qualification Often done in meeting w/coaches or? Extra bibs (1-16 or 1-24)

21 How to Organize a Sprint Important elements: Start crew need constant information (who advanced?) information from timing room Starter confident, strong voice (false start procedure?) TD and Jury positioned, separate tasks (see later slide) Announcing in communication (radio) with Chief of Race?
