Ach ! Always the same problem ! Of course, there are still many and many climbs out of the list, including the different sides of our BIGs. But, it's the main characteristic of our challenge : a closed list.
It means a choice, and to choose is always to delete something.
It's our default but it's also our quality.
If you want to add the altimeters of the different sides of passes that you climbed, you can subscribe in OCD (ordre des cols durs - cycloclimbing in UK) which allows the climbing of diffrent sides of the same mount or pass and adds the differences of levels (see our links in the website).
For my own, I'm member in CCC (cent cols club), OCD, UIC, BIG, CIMA,... Now, each climb is good for somewhere and the challenge BIG can keep its difference and what is its current success.
Best regards and thanks for your advice.
