brick
n.— «Yesterday I did what is known in triathlon parlance as a “brick.” Insert brick jokes here. A brick is two segments of the triathlon performed back-to-back. I opted to do my most challenging portion, the bike-run brick. That means a 10-mile bike ride followed by a 3-mile run. Don’t even get me started on the fact that the race will be a 4-mile run.» —“another brick in the wall” Mary Haley (Fairbanks, Alaska) May 9, 2006. (source: Double-Tongued Dictionary)
