Cross-country eliminator (XCE) is a mountain bike race format in which four riders compete against each other over a very short course. In each heat, the two fastest riders get to the next round, while the two slower riders are eliminated from the race. It is similar to four-cross, except that the course is not downhill.
Cross-country eliminator races have a maximum duration of 60 seconds. The format differs from the classic cross-country race both in its sprint character and the separation of the race into heats. The track itself is similar to XC tracks, going both uphill and downhill with natural and/or artificial obstacles.[1]
