[2] The fast times locked him in for Morocco's World Marathon Cup team in 1989 along with Driss Lakkim, Nourredine Sobhi, and Rachid Tbahi.

But he bounced back with a win at the 1989 Marathon de La Rochelle, which had been founded eight years earlier.

The race from Two Harbors, Minnesota, to Duluth along the North Shore of Lake Superior had clear skies and 60-degree weather for runners such as American Doug Kurtis, Brazilian Jose Cesar de Souza, Soviet Igor Braslavskiy, Swiss World Marathon Cup competitor Richard Umberg, and others.

[10][11][12] On a hot and windy day in Cleveland, Dacha prepared to race against Don Janicki, Simon Naali, and others in an international field.

He wore longer shorts and had a bottle problem that mixed up his race, though he still managed to stay ahead of Nivaldo Filho and Peter Renner.

As apartheid sanctions were lifted for South African athletes, Willie Mtolo overcame a strange, rushed start to take the win and Dacha chased Italians Walter Durbano and Luca Barzaghi closely to finish eighth in 2:13:35.

Instead of pulling away early, Dacha ran a tactical race, waiting until Sunset Boulevard (mile 22), to surge, and he crossed the tape uncontested in 2:20:02.

One winner had to be decided, and race officials determined that Viguera edged Dacha by an inch as he dove for the finish-line tape.

[27][28][29] In the 1995 Chicago Marathon, Dacha ran 2:12:05 to finish fourth behind German winner Eamonn Martin.

[30][31] Dacha continued running competitively as he climbed the age categories, finishing in the top of many race results through the globe, including Las Vegas, Salt Lake City, Monaco, Long Beach, Tampa, Toronto and others.

[32] He lived and trained in several locations, including Boulder, Colorado, and Flagstaff, Arizona, (with Salah Hissou for a time) before moving back to Morocco.
