Longest Winning Streaks?

Julio Cesar Chavez had his first fight in early 1980.

He 87-0 before he drew with Whitaker in late 1993.

He was 89-0-1 when he went into his fight with Randall in mid 1994, which he lost.

14 years and 90 fights without a loss (one draw) is quite a streak, even if his early competition was poor.

 

Monzon was undefeated for the last 13 years of his career I believe. Something like 81 fights.

 

SRR was "only" 35-0 when he lost to LaMotta. He continued on to 128-1-2 though , which was his record when he lost to Randy Turpin in 1951.

Pep was 62-0 when he lost to Angott in 1943.

 

After dropping a decision to LaMotta, Robinson went 91 fights without defeat. Then lost to Turpin.

 

Larry Holmes was unbeaten for 12 and a half years.
Pro debut on March 21st 1973, defeated by Michael Spinks on September 21st 1985.

 

Loi lost in Denmark against Johansen in 1952, he revenged that L 2 years later and he was undefeated until he was robbed against Ortiz in his hometown in 1960, that 8 years without a loss were 67 wins...

 

Pep was 62-0-0 or 63-0-0.

Marciano obviously was 49-0-0, Holmes was 48-0-0

Chavez had a VERY long one. Wasn't he like 85-0-0 at one point???

 

Chavez lost in 1981

If we are talking time:

Foreman went over 14 years unbeaten

Tony Ayala turned pro in 1980 and lost his '0' in 2000....
