During the 1960s and 1970s, most of the 100-mile races were held on oval tracks. Additionally, 100 miles were achieved during 24-hours races, usually also held on tracks. Running for 100 miles on an oval track seemed like an extreme oddity back then, even as it does today.

Beginning in 1978, an important track 100-miler started to be held, that became the premier track 100-miler. The race was held on an military base at Fort Meade, Maryland in America. It would be held there for twelve years. This 100-miler was dominated by Ray Krolewicz of South Carolina, who won it six times. Sadly, this race has been mostly forgotten in the annuls of ultrarunning history.
