The basic premise is:
-too late to build base and aerobic fitness for a race 6 weeks later
-maximize your Vo2max and lactate threshold gains in 6 weeks
-maximize core and muscle strength
-avoid injury for 6 weeks
The setup:
-find a track
-find a gradual, shortish hill of around 300m in length, preferably grass
-buy a tub of the best whey protein you can find
-buy lots of Gatorade
-have stopwatch
The main workout:
1) start with 1K hobby jog warmup, focusing on your turnover
2) stretch and stretch well, adding dynamic stretches at the end like leg swings
3) do maybe 4 short strides and whatever other biomechanical drills you wish to add
4) Do 600m at faster than your mile pace (preferably your target pace). So think 67 seconds for each 400m so that leads you to about 100 seconds (1 minute 40) for each 600m rep. KICK IT HARD for the last 100m of each rep. This means each of your 600m reps should be completed at faster than your target goal pace.
5) Rest for 2, maybe 2:30 minutes.
6) Repeat at least 5 more times. Even if you feel your pace starts to fall off and you can't do them in 100 seconds, keep going and keep pushing until the end.
7) Drink protein shake, maybe eat a banana, drink water.
8) Cooldown jog of around 1 mile
9) Stretch then immediately ice
10) Go home and stretch some more
Sample Schedule:
Monday: Hobby jog for 4-8 miles
Tuesday: WORKOUT
Wednesday: Hobby jog for 4-8 miles
Thursday: WORKOUT
Friday: Hobby jog for 4-8 miles
Saturday: WORKOUT
Sunday: Hard tempo of 4 miles followed by Hobby jog of 3 or so miles
*at least 1, preferably 2 of the WORKOUTS will be done on the hill you have found. On the hills, run for 300m on the flat buildup to the hill and end with the last 300m running on the hill itself.
**at least one of your hobby jogging days should be 8 miles, to constitute your "long run"
Also:
-Do abs EVERYDAY until your abs are screaming in pain.
-Lift weights on days you are not doing a workout (M-W-F). Focus on arms, shoulders and chest. Bicep curls, tricep extensions, dips, rowing/pulling machine and the bench press should be good. Do a weight at which you can do 3 sets of 12 reps each. You are building strength and power.
Disclaimers:
-this is a crazy stupid plan and you will end up injured
-you will need to taper for 1 solid week before your race
-you can increase the number of reps to the 600m if you are feeling good
-this is a short term plan and you are not really building much aerobic fitness so your "base" will continue to stagnate and you will have to do some serious mileage to make up for the loss of aerobic fitness later on
