Day 84- planning

No, did not do my walk as planned, just didnt feel like getting up in the morning and then didnt have time in the evening.
But did find a few things, looked up the half marathon preparation plans from Hal Higdon, Jeff Galloway and the coolrunning site, liked the Jeff Galloway plan the best, because :
1-it covers 17 weeks of gradually increasing activity and the other 2 are over 12 weeks.
2-only the long runs are long - the rest of his weekly workouts are all of the same length of maximum 45 min whereas with Hal Higdons program one has to do runs of 6-7 miles by the end of the program which means putting in more than 60 min of running during a weekday- not happening for me.
3-Also JG's plan has a very gradual increase in the length of the weekend long runs with going up and down the mileage slowly .
Disclaimer: I am not putting down the other 2 plans, this is just a reasoning as to why they would not work for us.
So from next week will start from week 4 of JG's half marathon plan for novice runners and should be ready for the May 3rd American River half marathon. The two 5k's we are planning to do will be a part of the training plan. Then from May 3rd till October 19th -will do the 6 month marathon training plan. Good
Calorie requirement for a moderately active woman: 2000 calories.
Woman 31-50 years of age.
Moderately active: walking 1.5-3miles per day at aspeed of 3-4 mph.
Referenced to a female with a BMI of 21.5
Source : www.webmd.com, browsed thru many sites and this was one which seemed most authentic.
Since my BMI is not 21.5 does this mean that if I do consume 2000 cal/day and be moderately active , I will lose weight and ultimately have a BMI of 21.5?
I guess so.
Run tomorrow.
