I'm attending a conference all week in Waltham, on radars. Interestingly, the Westin conference center is right on Prospect Hill. I didn't want to get skunked out of a workout two days in a row, so I threw a mountain bike an pair of rollerskis in the car. Instead of spending the last minutes of daylight in stop-and-go traffic on Rt 3, I decided to squeeze in a workout in Waltham before driving home.
The park is pretty small, maybe two miles long at most and a half mile wide. A paved rode runs end to end, gated at one end to prevent through traffic. Parking is at the base of a long abandoned ski area. I decided to ride first, so I could check out the road. I went right into threshold pace to warm up on my first climb. From gate to summit, about 330ft net gain can be realized in 0.82mi. Since I was on a fat tire bike, I went over the top on the Ridge Trail. Kinda chunky with the steps and all. I bombed down the paved road on the other side and turned around to go back up and over. I did this three more times, each time taking a different route back through the woods. My climb times were pretty slow, hovering just under five minutes. 24psi knobby tires and 8 lb Camelbak will do that. Didn't diminish the workout quality though. The last three climbs were solid VOmax efforts, which I haven't done in 10 days waiting for my chest to clear out.
Next up were my other set of wheels. Peak grades approached 15%, so this was going to be interesting now that my legs were partially tenderized. I used my Neiflheim rollerskis, which are pretty slow. My final push between the water tanks on the bike brought me close to the hurl threshold, but on rollerskis, I was at the hurl threshold almost immediately. This is where spring fitness comes from. Skiing is hard, even if it is on wheels on a paved surface. I did two rollerski climbs, in the 8-9min range.
First 0.3 miles is >11% grade.
How did I get back down? I hoofed it. Well, most of it anyway. I did not trust myself or speed reducers on such a steep grade. There were occasional cars coming up too, although none passed me in my direction during my two climbs. I passed a couple heading up during one of my climbs. Then I met them again on my hike back down. The guy was completely confounded, commenting that it would seem much easier to ski down instead of up. There was no way to explain that one.
Anyway, six seriously hard efforts up that hill made for a nice workout before the sun set. It might be the only workout I get in all week, now that I have some additional tasks to complete concurrently with the conference.
