I’m a male 5’7” 180 lbs. I’ve been riding my soul cycle at least 3-5 times a week for about 6 months building up my cardio. 45 minute rides. Got on the treadmill for the first time in a while a couple days ago and I’m now really worried about the marathon. Ran three miles but it took me 50 minutes. My pace did get better the longer I ran. I’m not trying to get some great time. I just want to finish to prove to myself that I can still do it now that I’m 41. Friend talked me into it but he’s a damn fitness Adonis. I played competitive sports in high school and throughout college so I have athleticism in me. Just wondering if it’s even reasonably possible to train for this in that amount of time.
