Sugarbush calls it the 31st Triathlon, but the event includes four parts instead of three.

They are running 5 miles, paddling 6 miles, biking 8 miles, and cross-country skiing 3 miles.

The running leg is on paved, rolling terrain. The paddling involves Class II whitewater. The biking section is on paved, rolling terrain with significant uphill stretches. The skiing is laps on an uphll/downhill course at the base of the ski area.

Event rules require running on the shoulders of the road where possible; PFDs for paddlers, and helmets on kayakers; and bike helmets for cyclists.

It's fun in the Mad River Valley for participants and spectators alike - and perhaps more enjoyable for those who watch.

Fee: $45. Register 4 to 7 p.m. April 4 in the Mount Ellen Base Lodge. Athletes must sign a waiver by which they agree to hold Sugarbush harmless no matter what misfortune befalls them during the event.

The race begins at 11 a.m. April 5.

Sugarbush also has a Kids Triathlon the day before, April 4, so youngsters 12 and under can taste the joy of victory and agony of defeat, although everyone who participates takes away the pleasure of athletic effort.

This event is broken into nine classes by age and gender.
