Hi,
I'm Heather.
I'm 5'3 (157 or 158cm)and I'd like to lose about 8kg, and get to a healthy BMI (under 60kg/132lb)
This is some of my story for getting to this point.

It's very long, I know. I enjoyed writing it, but don't really expect many people to get through it all

The Running Goal
I've spent the last year doing a lot of running to train for a hilly 20km race that I finally did at the end of August.
I've volunteered to help mark out the course for 3 years and each time I thought about how much I'd love to be able to run it. Last year I was quite unfit when it can around - running/hiking about 6km(with lots of stopping) to help make out the trail was really hard and left me sore the next day.
I decided it would be my goal to run it this year.

I spent the first month (September) just aiming to be active for at least an hour every day. I missed a couple of days, but did a lot more than I had been.

Then on the first of October I started running. I ran six days a week, because I wanted it to be a habit and not have to decide if I was going to run or not. I started out with 5 days of 2km running and one day of 5km. Then each week I added either to my long run or to a shorter one. For the first 12 weeks I only skipped one run!
I was addicted to the sense of progress and poring over my training log!

After that my training was not quite so consistent, I probably averaged 5runs/week. I had to take it very easy for a few weeks when I gave myself shin splints by (stupidly) doing a 17km long run, when I was only due to doing a 12km one.

I ran a flat half marathon (21.3km) in March in 2hrs8mins which qualified me to enter my hilly goal race.
I did another half marathon in May, it was hilly, but not as steep or technical as my goal race. I did it in 2hrs45mins and was in the last third of runners.

Then Wonderland run (THE goal race) came around on August 25th. It was good, I ran hard the whole way.
The start is so steep that the first 5km took about an hour, with me puffing hard. Having run in the area quite a lot I was more confident with the footing than a lot of people and I took the downhills a lot faster than the people around me (many of whom caught me on the next flat or uphill).
I finished it in 2hrs43mins, and in the first third of runners (first 20% of women).

And it was done.... What next?

The New Goal:

I definitely didn't want to stop running completely, but I wanted a new goal.
I'd like to get faster at the 5km - but that goal doesn't inspire me the way my goal race did.
I'd like to lift weights regularly again and get strong again. I've been aspiring to 3sessions a week all year, but running came first and I probably averaged one session a year. This goal didn't inspire me enough either - it felt like going over old ground and trying to get back to where I had been before.
I really wanted to be able to use that same sense of purpose I'd felt when I started running.

And I thought of weight loss. I was 67kg, and sometimes fluctuated up to 68kg - the heaviest I've seen on the scale. I've wanted to be at a lean and healthy weight and have tried half heartedly to get there for for 10years (I'm 26). My weight is 'normally' 65-66kg(143-145lb), and has ranged from 63-68kg(139-150lb) over the years.
To weigh under 60kg and know what that felt like.... I want that.

The Plan
Since it worked really well when I took a month to prepare myself before I started running last year I thought I would do the same thing this time.

My goals for September:
1. Record all my food consumption on MFP (without trying to limit myself) to establish what my baseline is.
2. Lift weights 3x per week - I think this is vital so that my weight loss comes from fat and myuscle is (mostly) spared.
3. Continue to do other physical activity 5days per week. I was aiming to run 5x per week,so this will save me lots of time - now if I go for a walk or a bike ride I don't need to do a run as well. (Also no running milage goal).

The longer term plan is to stick to a calorie goal and lose 1kg/month, which would see me under 60kg by May 1st next year.
I think I'd like my maintenance range to be 57-60kg(125-132lb), but I'll see how I feel when I get there.

3 weeks in, I'm feeling good, I've recorded my food everyday and met my exercise goals. I got impatient about actually losing weight though. I took two weeks of baseline eating whatever I wanted (~2350net calories) and subtracted 250cals/day for week 3 (2100 net calories goal).

My weight was 65.8kg this morning.
I'll stick with 2100 calories from here on in and see how I go.

Lovely to meet you all and I'm looking forward to sharing the journey with you here (Probably in less words from now on )
