My new program has me splitting my met-con and my event training. It's working well for me. I can't do weight work and event training on the same day. it just takes too much out of me. When I was younger I could do it. But not anymore.
Right now I'm in my "Strength and Conditioning" macro cycle - 10 weeks (I'm on week 8 of 10). 4 days of weights - 1, 2, 4, and 6. And 3 days of event training and met-con - days 3, 5 and 7. The met con is primarily extended (longer in time) sets of kettlebell work mixed with normal cardio (jump rope, jog/walk, sometimes I do handle work (sports specific stuff)).
My next macrocyle as me doing 3 days of weights and 4 days of event training and met-con. The met-con at that phase will be more GPP centered. And the weights will be lighter.
don't know if that helps at all?
All the best,
