Dan Martin is hoping that home advantage will work in his favour as the Tour reaches its first summit finish in the Pyrenees today.
Stage 9 is the final ride before the race's first rest day, and provides the peloton with its stiffest challenge yet, including three Category 1 climbs and the Hors Category incline to the finish at the Andorran ski resort of Arcalis.
Martin's fine form was again on display as he finished second behind new yellow jersey Chris Froome on Stage 8, and the Irishman, who recently relocated to Andorra, will look to be a key player once again on roads he has come to know very well.
"This is my environment, in the Pyrenees, I love it," Martin told The Cycling Podcast.
"It's still only the first week and I've always been good in one week races so this is still what I'm good at. I still need to prove myself in that last week.
"It's on my home roads. I think we pass 600 metres from my house and obviously I know the climb really well.
"Ordinarily it's not the most decisive climb, it's not the most difficult climb of the race, but I think with the impact and fatigue that's been brought on by the last eight days' racing, and how difficult the stage is as a whole, and with the heat as well, it's definitely going to take its toll on people who haven't recovered properly."
Froome took his rivals by surprise by jumping off the top of the front group at the summit of the Col de Peyresourde, gaining 13 seconds on the descent and seizing the race lead.
Martin, who trails the Briton by 17 seconds on the overall classification, admitted he had not been expecting the move, believing Froome was merely padding his King of the Mountains tally, having also moved to pick up points on an earlier climb.
"I saw him going and though he was going for the King of the Mountains points and thought, 'that's strange', but then he just kept going over the top, and maybe that's what the other guys were thinking as well."
