Pre-Race Meeting
A pre-race meeting will be held 15 minutes prior to the start of each race. All team captains and solo riders must attend.
Starting Procedures
Each starting racer must be on the starting line at least 5 minutes before the start time. The start will be a Le Mans style start. (Running to bike)
Helmets & Equipment
All competitors are required to wear an ANSI and/or SNELL approved helmet at all times during competition as well as when pre-riding or warming up on the course. Riders must wear proper riding attire, including a shirt and fully-enclosed shoes during competition. Each racer is responsible for having their bike in good operating condition, including but not limited to: two fully-functioning brakes, plugged handlebar ends, NO hazardous attachments including kick stands and reflectors, adjusted hubs and headset, true wheels, and a sound frame (no cracks, severe bends or dents). The race directors may remove any racer from the start whom they feel is attempting to compete on an unsafe bike. Walkman, headphones and other personal listening devices which may interfere with a racer’s awareness of other racers and their surroundings are strictly prohibited.
Lighting
Lights are recommended for all riders starting a lap at or near sunset.
Support
It is highly recommended that you bring your own food and water. Racers can receive food and water from anyone and anywhere on the course. They can also receive mechanical support from anyone, even parts from another bicycle, or a different bicycle, as long as they have the owners permission. They must have the number plate attached to the bicycle they are riding. All racers should be clear of the trail for all support and repairs. Racers riding have the right of way.
Short Cutting
Deviation from the marked course will result in disqualification unless the competitor reenters the course at point of exit. This includes ducking under any flagging marking the boundaries of the finish chute. Short cutting the course by any racer will result in disqualification of that team.
Postponement of Race
A race may be stopped and/or postponed by the race director in case of severe injury to a rider. Racers failing to heed the instruction of medical personnel attending to an injured rider will be disqualified!
Weather Delay
A race may be delayed, stopped or canceled at the discretion of the race director due to heavy rain. The race will be restarted in the order of the racers last completed lap with timed spacing. In the case of a race being canceled, the rain date for the Series is TBD for 2024. An event is considered complete at 6 hours 1 minute in the 12 Hour/100 Mile events and 5 hours 1 minute in the 10 Hour / 75 Mile events.
Raffle
Some events in the Wisconsin Endurance Mountain Bike Series may have a day of raffle. Tickets will be sold only on the day of the event and the drawing will be held later in the day. You must be present to claim your prize.
Public Access
Some of the trails we race on will still be open for the public to use during the event. The race director will mention if the trails are open for their specific race. Please be courteous to anyone that is using the trail, and be considerate when preparing to pass them. PASS WITH CAUTION. Remember, they could be inexperienced riders that have never encountered a group of racers before. Think SAFE!.
Clean-up
Take out whatever you bring in, there will be no rubbish removal. No littering on the course. Any rider reported for littering will be disqualified.
Scoring
See race links for race end times as these tend to change from one event to another. If you do not think you will finish your last lap by that time, it is recommended that you do not start that lap. Any lap finished after the ending time will not count to your total. The placing of teams will be by the total laps finished by the ending time, and the finish time of the last lap completed. (Example: Team 1 completes 13 laps at 7:45PM Team 2 completes 13 laps at 7:57PM. Team 1 beats Team 2. But Team 3 completes 14 laps at 7:59PM, Team 3 is the winner.)
Awards
Awards will be presented about 30 minutes after each race ends.
Series Scoring
For 2025, a new tabulation will be used for calculating the overall series points. A competitor will earn points at each event. The main variables are Time, Distance, and Number of competitors in each category & distance.
(Winning Time / Finishers Time) x (Total Miles) x (# of Competitors in category & distance)
For relay Teams competing at the Underdown Trail Races, their Team points earned for series scoring will be based on the average points of all team members. (i.e Rider 1 earns 60 pts, Rider 2 earns 30 pts, Rider 3 earns 36 pts, Team earns 42 pts for the event towards series scoring.)ALL Competitors who register for a “Series Registration” are eligible for overall series points and a series award. To keep things simple we have removed the minimum requirement for completed races. The more you race, the more you earn!
A competitor may earn points for a race due to a DNF caused by a mechanical breakdown at a value of 50% of the lowest scoring competitor of the same category & distance. WEMS will do its best to keep track of all competitors and the races they participate in over the season, however, it is the responsibility of the competitor to notify WEMS in the event of any missing points.
