Shovel = bike? No sir. Not hardly.
I'm embroiled in a massive home project involving demo'ing half my house, moving the remainder about 50 feet, putting it on a foundation, then building a new 825 ft/2 addition. I'm currently digging foundation trenches.... with a shovel. Heavy equipment would be too invasive at the new homesite.
So for the last week or two it's been cutting trees, digging out stumps, taking out old fences... in a heat wave no less.
I get done with a day and I'm too whipped to ride. It's an ugly "whipped", too; massive sweat all day and beat up lower back. Should be done tomorrow (with the trenching).
I'm getting huge workouts, but MAN do I miss riding!! On the flipside being in great aerobic shape- and used to sweating in the heat on my climbs- has given me the ability and stamina to really hit this hard and long every day.
I did ride with a buddy after a long day of this stuff the other day. I was totally whipped as we started... the first long climb was like "just shoot me".... but by the end (30 miles) I felt great. Need to remember that.
