I suggested the change of venue for this week’s long run
because I wanted some hill work and I wanted a break from our usual hill run at
the Cherry Creek Reservoir. It has been
a particularly mild winter so far and the Highline Canal Path is virtually
clear of snow. The path is less
demanding on our old joints, but is virtually flat. The spring marathons we are running are hilly
and require adequate training.
It is seven miles from the parking lot to the gate at the
top of the dam with an elevation gain of about 800 feet. In comparison, the Newton Hills in the Boston
Marathon rise only about 200 feet over six miles. Those hills culminate with Heartbreak Hill which
rises only 88 feet (from an elevation of 148 feet to 236 feet), but it comes in
the portion of a marathon distance where muscle glycogen stores are most likely
to be depleted at mile 20.
So, we train on hills to acclimate our bodies to climbing. Running uphill trains the lungs; running downhill
trains the legs.
Uphill running teaches us to run with much better
technique. It forces us to lean forward
and to run with shorter steps with a higher stride frequency. It also trains us to keep our weight on
the balls of the feet.
When running downhill, the tendency is to try to “brake”
which puts a lot of stress on the leg and hip muscles. We need to train ourselves to keep some of
the forward lean so we don’t tax our legs.
The Boston Marathon course elevation drops about 220 feet
from the crest of Heartbreak Hill to the finish. Anyone who has ever run the Boston Marathon
can tell you how hard it is to run down Beacon Street.
My spring marathon is the Colfax in May. I came across an ad for the inaugural edition in
2006. “It's flat, with elevation gain of
only 279 feet. No Heartbreak Hills.” Whoever wrote that should be pummeled with Pumas. While it is a fact that the finish
was 279 feet above the start, the elevation chart looks like a hockey
stick. That course rose 538 feet over
the last nine miles including about 150 feet in the last mile.
This year’s edition of Colfax has an elevation gain of 548
feet, which is spread over about 15 miles.
The nice part of the course is that there is a six miles descent from “the
Glenns” down Colfax Avenue to the Platte River.
Sunday morning my legs were feeling the effects of the hill
workout. This means the workout was effective
and it means I have more work to do.
