Ralston began his coaching career in 1952 at San Lorenzo High School in San Lorenzo, California, just south of Oakland. He subsequently was an assistant coach at Mt. Diablo High School in Concord, California. in 1953 and 1954. He then spent three seasons as an assistant coach at Cal from 1955 to 1958.

Ralston moved to Stanford University in 1963 and, over nine seasons, built a mark of 55–36–3. In his last two seasons, 1970–1971, Ralston's teams won two Pacific-8 titles and notched back-to-back Rose Bowl victories over Ohio State and Michigan, both of whom were undefeated coming into the Rose Bowl game. Under Ralston's tutelage, Stanford quarterback Jim Plunkett won the Heisman Trophy in 1970.

In 1972, Ralston departed the San Francisco Bay Area again, this time for the Rocky Mountains and the Denver Broncos. The Broncos finished with a 5–9 record in 1972. In 1973, a year which included the "Orange Monday" game played in front of a prime-time national television audience in which the Broncos came from behind to earn a tie on Jim Turner's 35-yard field goal, Ralston coached the team into first place with a 6–3–2 record. With their first winning season in franchise history under their belt and with the AFC West title on the line, the Broncos' season ended with a 21–17 loss to the Oakland Raiders. Ralston was the UPI's choice as AFC Coach of the Year after Denver achieved its first-ever winning season at 7–5–2.

In 1975 the Broncos finished with a 6–8 record, but the following year the team improved and finished with a 9–5 record. The record was not, however, good enough qualify the Broncos for the playoffs. In five seasons with the Broncos, Ralston guided the team to winning seasons three times and an overall record of 34–33–3; despite this, he never went to the playoffs during his Bronco (and NFL head coaching) tenure.
