Sounds like the running is your priority, so I'll keep that in m ind in my reply.I don't see anthing wrong with what you are doing. With respect to recovery, just keep a close eye on your intensity with the weights. If you have problems with recovery fron the strength training, just dial the intensity or volume of the weights back a bit, but frankly, I don't see 3 5k's cutting into your energy reserves all that much, and don't see that it would effect the cns (central nervous system-this is what's necessary for recdovery from weights) all that much at all. As far as effctingleg strength, I don't see that happening for your purposes. Now, if you were a Powerlifter, and trying to post a big Squat, it wouldn't be adviseable, but it sounds like you're just going for general fitness, and it looks to be a solid program, for me anyway.
