Hi there!
I graduated c25k in February and felt that no way could I ever do 10k! But recently I made it to 8k so I think I am finally ready to go for it and build up to 10k!
My main reason for not doing so before is because out of my three runs a week I can only run longer than 40-45 minutes on the weekend.
8k took me 55 mins (with the 5 mins walks either end) so I estimate 10k taking a max of 70-75 mins.
I'm just not sure how to build up? Maybe adding 5 mins to my one long run a week for like 4 weeks? Then add another five mins etc?
