I have tried it ! It ' s also nice , I agree . <| sep |> Maxeffort runs are going to be mostly pointless in your situation . You already have strength and highaerobic efforts covered with your climbing , and your goal is aerobic fitness , so run aerobically . Given a 2000 5 k which , btw . , is pretty damn fast for a beginner , I suggest you do your runs at about 3000 5 k pace , i . e . , ridiculously easy . Doing about 3 runs per week at this pace , somewhere around the 6 mile mark if you can stomach that less if you notice fatigue building up , should be enough for the foreseeable future . <| sep |> Reminds me of feedback by kanye lol . I like it a lot . Only minor criticism is those little fast hihats are super piercing . Might be cool to vary that synth arpeggio too just to add some interest . Here ' s mine , just a short little trap thing forthebattletournament
