Can do this? Frankly no. While I have no doubt of your desire, please understand that your goal is only possible for a very elite group of athletes.
To put this in better perspective, the 2008 US Olympic Trials used 29:00 as it qualifying standard. Leading up to the June trials in Eugene only 40 guys in the entire nation were able to break 29!!!
Or said another way, your stated goal happens to be faster than the existing World Record for women. To break 29:00 you will have to run 25 consecutive quarter-miles 69-sec pace. And Dr. Daniels' esteemed VDOT table indicates that you'd need to run a mile in 4:10 in order to possess the leg speed to give a sub-29 effort.
Bottom line: unless you are a former collegiate All- American, training under the watchful eye of a national-class track coach, and logging 100+ miles per week, your chances of EVER breaking 29:00 are basically non-existent. Sorry.
I would encourage you to instead strive for a sub- 35, which will still require tremendous natural ability and intelligent preparation. Trust me.
