A sleeping pad is not a mandatory item for racers in RacingThePlanet Ultramarathons but is highly recommended. Select a small size to save weight or a regular size for added comfort and warmth. Self-inflating pads are light, but can be difficult to eliminate air for packing and can puncture. Tents provided in the race do not have any ground padding. The sleeping pad is also highly recommended for insulation against the cold and possible wet ground at night.
