And they do so safe in the knowledge that they won't be relegated to the PRO D2 after they picked up a bonus point in defeat to Montpellier to move six points clear of 13th placed Brive with just one league game remaining.
Relegation has been an unwanted cloud hanging over the club throughout a disappointing domestic season but legendary France and Biarritz full back Blanco insists there is now only one goal his team are targeting as the season draws to an end.
"I honestly wasn't too worried because I was personally convinced that we weren't going to be relegated but the good news is that we have secured our status one week before we expected," said Blanco.
"We will now be able to focus totally on the Amlin Challenge Cup final."
Amlin Challenge Cup glory would add a real gloss to an otherwise frustrating campaign that has seen Biarritz win only nine of their 25 Top 14 ties to date.
But the rising profile of the club's younger generation and the manner in which Biarritz are ending the season - with five league wins, two bonus point defeats and two more Amlin victories - has convinced Blanco that good times lie ahead for the Basque outfit.
"I am convinced about the strength we have at Biarritz Olympique," added Blanco.
"We could have been relegated by some freak accident but this was only really when we were missing a lot of players. Since the squad has been back to near full strength we have had some good results in the last eight or nine games. And even when it was difficult for us we always kept moving forward by displaying our true values and our young players did well for us.
"The future should be very good. The beginning of the season was difficult with the World Cup when all our young players had to be a part of the first team. Things weren't perfect but that was to be expected because these youngsters still need to learn. It was important that they got game time, though, and that's good for the future.
"When you look at the team that played against Montpellier you can see that the back row was full of young players (Raphael Lakafia and Wenceslas Lauret are 23 and Talalelei Gray is 22), while 21-year-old outside-half Jean-Pascal Barraque showed he has a very good kicking game."
