Speeding up recovery?

IMMD is only 8 weeks away, so I'll be brutally honest.  That's not a very good way to train.  Some assumptions need to be made about your current fitness level and I'm assuming you don't have a significant injury history, but consider taking an Ironman training plan, such as the 12 Week Half Iron to Full Iron bridge plan here on BT, or Gale Bernhardt's 13 Weeks to a 13 Hour Ironman plan, and doing the last 8 weeks of it with some tweaks as needed based on your ability to recover.  If jumping into one of those plans 4 or 5 weeks in is above your current fitness level, then you may need to start at week 1, and tweak the sessions so you're able to skip a week here and there to compress the schedule to 8 weeks, but then you're increasing injury risk.

Training doesn't increase fitness, it breaks the body down.  Recovery after training is what increases fitness.  Doses of training stress alternated with recovery for fitness adaptations to occur is what needs to happen during training.  If you're having trouble recovering, you're either not allowing enough recovery or you're trying to take too large of a "dose" of training stress at a time.  Too much training stress at a time causes you to not be recovered by the time the next training session is scheduled.  Allowing for more recovery doesn't mean more days off completely.  It means maximizing sleep, optimizing nutrition and hydration, and minimizing other sources of stress, such as work, family, financial, etc.  The objective of your training should be to apply the minimum amount of training stress that will induce the desired fitness gains.  For someone in your situation with only 8 weeks to go until the race, who is having trouble recovering, and appears to have marginal fitness, I'd also eliminate strength training completely from now until the race (assuming it's not a custom program designed to address a specific functional issue a'la physical therapy or corrective exercise).  It's additional training stress that's not specific to your needs and will only impair your progress at this point, because that time is better spent either doing more s/b/r or recovering from s/b/r training.
