Bi6 al – I was going through the same thing as you bud, my mates are now all quick bikers, racing or doing epic rides most weekends and are leaving me for dead. I have a wife, a 2 year old boy and a 3 month old boy.I'm lucky that my wife is also a biker and despite the fact that she's wanting to ride herself, still let's me out for a 2.5 hour night ride with the boys on a Tuesday. She know's what it means to me and at the minute with all the turmoil and madness in our house, I live for that time.
It was starting to bug me however, that this 2.5 hours was becoming less and less fun because i was getting left behind, or spending it blowing out my ar5e for the entire ride, and I was getting a bit dejected about it all.
I bought a new turbo trainer about 6 weeks ago, it is amazing how they have progressed, It has a watt counter, speed, time distance and other gubbins to tell you how shockingly hard you need to work.
I also have 3 season box sets of Prison Break to trawl through, an old laptop to play it on, coupled up to a docking station so I can hear it, my phone, a fan,the baby monitor, 2 bottles, a towel….. it looks like a flight deck of some kind, but the upshot of all this is, I've lost eight pounds,my waistline is shrinking, my climbing has improved, my power is improving, I'm not quite up with them yet, but I think they're getting worried.
The main thing is I've noticed a distinct difference and my enthusiasm's coming back.
I do 3 x 50 minute sessions a week (three episodes), I plan to start introducing intervals because even with distractions, they are the longest 50 minutes of your life (and I used to race cyclo-cross!!!)
I have also noticed a few articles in mags which say that the new thinking is that intensity can have just as much if not greater affect than long sessions, which I guess is a good thing if you can learn to suffer on a bike (which if you're coming back to the sport you probably can)Y
You get out what you put in, but despite the grimness of turbo training, the constant resistance I'm convinced, makes the best use of whatever time you can dedicate to it, and pays dividends on real rides and I think you'll be surprised how quickly the difference comes.
Stick at it fella, and just try and find some way of making the sessions more bearable. If you find any groundbreaking ones, feel free to share them on here.
P.S Something that has worked for me, keep a diary of your sessions, and your weight on a week by week basis. The progress when you see it written down really helps motivate you to keep it up, and gives you a kick up the bum when you feel like sherking off.
