Help/Advice on racing an OLY During Week 16 of 20 of my HIM Plan

On September 27th I have an OLY. I am training for a HIM which I'll race on October 25th. The HIM is my A race of the season and my first HIM at that. I would love to improve on my OLY performance as this will be the first race I've ever gone into with adaquate and consistent training. At the same time, my focus in on my HIM and I don't want this OLY to adversly effect my final 5 weeks of training leading up to my A race.

I'm not sure how to approach my training leading up to the OLY. I invision a slight taper and slight recovery period following this race. Basically this is what my plan calls for the week of the OLY and I'd like some advice on how to handle what is required for the HIM but also adjust it so I can perform well in the OLY.

Here is what the plan calls for:

Mon: Rest day

Tue:Run:Raise LT. Race Specific. 60 minutes. WU: 10' MS: 5x5' at LT w/3' recovery. CD: 10'. Swim: Speed. 60min.
2000M. WU: 300 & 6x50 on 10" rest. MS: 12x100 w/ 20" rest. CD: 200.

Wed: Bike: Bike Strength. 90' ride on a hilly course. Push the uphills and recover on the downhills. HR on the uphills can hit low Z4. Keep HR in Zone 1-2 otherwise.

Thu: Run: Run Base, Endurance. Run 45' on a flat course or treadmill. Keep HR in Zone 1-2. Think about form and running pretty. Stretch when done and add in Core 1, 2 or 3. Swim: Endurance,70minutes. 2900M. WU: 300. MS: 4x200 pull with 30" rest. 8x100 with 15" rest. 200 kick. 6x100 on 10" rest. CD: 200.

Fri: Bike: Recovery, Easy spin for 60' in small chain ring. Do this after a long run or race if one is scheduled.

Sat: Bike:Raise Bike LT - KEY WORKOUT, 210minutes.Long easy ride. During the ride - 3x30' at Zone 3. Recovery is 10' easy spinning. I want you to simulate race effort during the 30' blocks. You must end with a hard 30' effort and go right into the BRICK. Run: Run 20' on a flat course or treadmill after bike workout. Keep HR in Zone 1-2. Stretch when done.

Sun: Run:Run 80' on a hilly course or treadmill. Let the HR get up to high Z3/low Z4 on the uphill and keep HR in Zone 1-2 otherwise. Stretch when done and add in Core 1, 2 or 3. Swim:65 minutes.  3600M. 
WU: 500. 3x100 on 20" rest - build each 25 to go faster. 3x100 on 25" rest. MS: 5x300 on 30" rest. Try to make each one faster from 1-3, then 4-5. 200 easy 6x100 w/paddles on 20" rest. Make each one faster again with #6 being faster then #3. CD: 200.

I'm thinking I can move Sunday's swim to another day in the week that doesn't already have a swim. I can do Friday's recovery ride on Saturday before bike drop off and packet pick up. I could push the long ride back to Friday. I'm not sure what to do with Sunday's long run, move it to Wednesday maybe?

I really have no idea how to approach this. I know I can't do it all but I'm unsure of what is necessary and what shouldn't be skipped. My logs are current and I've been doing a pretty good job at hitting my volume with the exception of the last two weeks where I was sidelined due to some tendinitis in my knee. Things are back to normal now.

Thanks for the help and sorry for the long post!!!
