I have a couple of questions!
I was talked into taking part in a swim challenge. We started about 6 weeks ago and I've now got the swimming bug 
During the challenge, I was going 3-4 times a week. The challenge is now completed but I'd like to continue going because I really enjoy it and it is starting to make quite a difference to my body shape which I would like to encourage as much as possible.
First question, is once a week often enough to go to keep up the fitness/help with weightloss (I'm also reducing my calorie intake). I've been struggling to get to the pool over the holidays but find it easier during term-time. However, I've done very few of my normal jobs over the last few weeks because every spare minute has been spent in the pool. I need to find a better balance.
Second question, when I started the swim challenge, I could only do 4 lengths
. I fairly quickly built up to swimming a mile each visit. However, I'm not getting any quicker. I could probably swim for longer but it takes an hour to swim a mile and I am really quite bored by the time I've done that. I just thought I should be getting quicker or maybe I should keep increasing the length of time I'm swimming.
Any suggestions?
