Table schema:
CREATE TABLE table_name_78 (leader_at_the_summit VARCHAR, finish VARCHAR, start VARCHAR, stage VARCHAR, category VARCHAR)

Question: Who was the leader at the summit when the stage was larger than 14, the category was 1, the start was Saint-Girons, and the finish was Cauterets?
SQL: SELECT leader_at_the_summit FROM table_name_78 WHERE stage > 14 AND category = 1 AND start = "saint-girons" AND finish = "cauterets"
