specific question about cardio...

[DeniZen]

some stats/info:

I'm pretty much a noob to all of this....better late than never!

54 year old male
5'-9"
172 lbs.
BF% +/- 13%
3 days weight training
3 days road bike/spinning bike/abs
1 day rest
Diet is clean/low carb/800 day caloric deficit
All natural...have gear but its staying on the shelf
241 lbs> 2 years P90x> 2 months weight training + bike = 172 lbs!

Body fat is getting low and I'm ready to attempt to add some muscle. I will be changing to a caloric surplus and more carbs over the next few weeks.

My question is about my road bike and spinning bike activity. I've been consumed with getting BF% very low, and currently cycle 100+ miles per week. Some of the climbs are hardcore with huge heart and leg pumps. Between the spinning bike and road bike total time is about 5-6 hours per week.

I would like to put on about 20-25 lbs of muscle over the next year, keeping my BF% as low as possible.

As I ramp up the calories/carbs do I need to scale back the cycling?

Thanks
