Been off running for 6 weeks now. I have been cross training in the pool, elliptical, and bike 60-90 minutes a day monday-saturday and 90-120 minutes on Sunday usually all bike. I usually hold heart rate steady in the 120-140 bpm range cant get any higher unless im swimming. Still have been hitting core hard during this time. I will be starting up running again next week slowly and fill in the volume that I can't run with more cross training. Is it possible to make a quick comeback fitness wise by xc? How much fitness can I expect to retain from my cross training? Looking mostly for ppl with experience x training for extended periods of time.
Also I've had no pain at all cross training.
