HIM training, 4 weeks out.

Hello,

I am looking for a little advice on how far I should push it over the next few weeks leading up to the Muncie 70.3 on July 13th. I'm a little worried maybe I haven't put in quite enough time on the bike or run. My last couple weeks have had one long ride (50-55 miles) and two moderate rides (one 25 miler at a high intensity, and another 35-40 miler at race pace or above). My running has been about 25 miles a week (one long run 13-14 miles, one medium run about 8 miles, and anywhere between 1-2 short speed runs 3-4 miles at the highest pace I can run and still throw in strides). My swimming is pretty consistent, one 2500 meter swim, two shorter days with a lot of speed work mixed in. Do I sound like I'm on a good track 4 weeks out? It is probably a little late to change it, but does it sound like I should be alright to complete it? I'm not looking to set the world on fire, would love to finish around 6 hours. My nutrition seems to be there, my legs are a little sore getting off the bike after a pretty good 50+ mile ride, but seems to get better each time. Lastly, when should I start to shut it down and taper? I don't want to lose any fitness, but also don't want to be zapped coming into the race. Do I sound like I'm on a good track? Thanks for the long read, I look forward to hearing from those more experienced than I in the subject (pretty much everyone).
