Since I first started running in high school, my training
has been predominantly on the roads. The
high school cross-country races were on trails, but all of my training (and
marathons) occurred on asphalt/concrete.
When I started training in April to pace a runner in the Leadville 100,
I transitioned my training to the trails.
Training on the trails was primarily driven by the need for
“specificity” – or training on the type of terrain one would be racing (pacing)
on. Leadville has come and gone, but my
plans are to continue running on trails, as it’s a hundred times more enjoyable
than running on the road.
With the focus on trail running, I decided it was time to
get proper trail shoes. My current running
shoe is the New Balance 860v2 (9.5 EE).
I don’t remember exactly, but I believe it’s a cushioned, motion control,
road shoe. I absolutely hated it on the
roads because it was too stiff and clunky, but loved the stability on the
uneven, rocky trail terrain. The cushioning
also helped on the long runs, especially as I tired (and my form went to hell). One drawback of running on the trails with a
road shoe is the open mesh. While this
provided excellent ventilation on hot days, it also allowed a lot of dirt to
permeate the fabric, creating a nice muddy mess (and increased friction). The 860v2 also has a 12mm heel to toe drop,
making it impossible to run with a biometrically efficient forefoot/midfoot
strike. The latest trend is toward
“minimalist” running shoes. Minimalist
shoes (or barefoot running) encourage a more efficient running form. I won’t go into it here, but read “Born to
Run” for more information. My initial
venture into minimalist shoes was the Merrell Barefoot shoe. In short, the zero heel drop and minimal
padding were a bit too extreme for me.
The zero heel drop puts a lot of strain on the Achilles tendon and
requires a lot of time for the body to adapt to it. I also desired more forefoot
padding/protection. I decided to try the
New Balance 1010v2 shoe instead. The
1010v2 is a minimalist trail shoe, with a 4mm heel drop, a bit more forefoot
padding, and a rock plate for protection from…well, rocks. This shoe filled the happy middle-ground
between the armor-plated protection of the 860v2 and the minimal protection of
the Merrell.
I ran a couple of flat, two mile test runs in the New
Balance 1010v2 shoe to ensure I wouldn’t have Achilles/lower calf problems with
the 4mm heel drop. The short test runs
felt fine, so I tested it on my regular seven mile trail route on Monday to see
how they felt going uphill/downhill and on rocky terrain. I increased the distance today, running my
ten mile trail route. My initial
assessment is positive. The shoes are
light and agile, and fit like a glove (not clunky and stiff like the 860v2). I’m also able to maintain a faster turnover
on downhill sections. The huge heel and
12mm heel drop on the 860v2 caused the heel to strike first, especially on
downhills. The 4mm heel drop on the
1010v2 allows for a forefoot strike and a much faster turnover. Additionally, the tighter weave in the fabric
keeps most of the dirt out of the shoe. My
only concerns right now are: 1) how well they will ventilate on hot days; and 2) how they will feel on long runs. The weather forecast calls for 100 degree
weather on Saturday, so I may test them out on a 20 miler. This would test both concerns. We’ll see…I may play it safe and opt for the
860v2.
Here’s a summary of my run today. The faster turnover is evident in the faster times on the downhill sections.
