Climbing a Mountain

I had been planning to climbing (or, "I had planned to climb" or "I had been planning on climbing) a mountain with two of my friends for a couple of weeks.
But today it was rainy and cloudy so we gave up to carry on our plan (or "we decided not to carry on with our plan.)
I didn't want to take them to the (or "a"?) mountain on such bad weather day a day with such bad weather (or "such a rainy/cloudy day") because they are beginners of climbing (or, "they are practising climbing"), bad weather would make them lose their interests for climbing ("bad weather would put them off climbing" = better).
Then ("so" = better) we changed our plan, we and went to have lunch at a nice restaurant.

よく　やった！　えいご　で　がんばって　ください！
