As mentioned above people spend very little time reading a CV so you need to make it really punchy.
* Name + contact details at the top
* Relevant work experience (highlighting skills, tailored to the job you're applying for. Bulleted list of the key things you did in the role, keep the sentences short and sweet!)
* Education
* Small section on interests, hobbies etc, good to highlight anything particularly impressive you have done. Being a climbing forum you should hopefully be able to put something quite interesting here!
Exactly 1 page unless you have 15+ years of relevant experience and you're going for a very senior role, then you can stretch to 2 if you feel it is necessary.
Ditch the personal statement, that's what a cover letter is for and you're using up valuable space to say exactly the same things as everyone else!
