Wow -- what a great ride! That was my impression the first time I used the Salomon XT Wings trail running shoe, and seven pairs and a couple thousand miles later, the XT Wings is still my shoe of choice for longer trail runs. Now the shoe has been upgraded to the XT Wings 2, and the good news is Salomon listened to the feedback from runners, and made a very good shoe even better.

One of the most obvious changes in the XT Wings 2 is the change from an asymmetric speed-lacing system that would sometimes fray, to a symmetric speed-lacing system with lower friction eyelets. None of my Salomon trail shoes with symmetric lacing have had lace-fraying issues, and these new laces look bombproof!

Update 07/05/10. I now have about 190 miles on each of three pairs of Salomons with the the new eyelets (XT Wings, XT Wings 2 & XT Hawk 2), and I've had no problems with the laces fraying.

Not so obvious until you run in the shoe is the redesign of the toe cap to increase flexibility. I thought the gait transition was smooth in the original XT Wings, and it is even better now. I was also happy to find that my new pair of XT Wings 2 (US Size 9.0) weigh 26 oz., which is a bit less than my first pair of XT Wings.

The shoes felt great on Sunday's Trippet Ranch loop; they had that familiar XT Wings' combination of comfort, smooth ride, cushioning, traction and support.

It's funny the things you think about during a race. Running down the Chumash Trail in the Bandit 30K on Saturday, one of my thoughts was, "Wow, these may be the most comfortable trail shoes I've ever run in."

I purchased my XT Hawk 2's from Zappos a couple of weeks ago. Right out of the box there were several things I liked about the shoes:

• They are light. My pair of US size 9's tipped the scale at a light 22.3 oz. This is about the same as the Salomon SpeedComp. 
• The shoes fit well. No weird seams, pressure points or other problems.
• The updated speed-lacing system is symmetric. It has no offset lace anchor across the toe, and uses a new eyelet design. I've never had Salomon speed-lacing fray on shoes with symmetric lacing, and the new eyelet should make the laces even more bombproof.
• The outsole looks nearly identical to the sole on the XT Wings, which in my experience provides a good balance of traction versus predictability.

Out on the trail, the first thing that stood out was the shoe's cushioning. It feels like the shoe has more cushioning than either the original XT Wings or SpeedComp. The heel is particularly well cushioned, but for mid-foot strikers like me, there is also plenty of forefoot cushioning.
 
What I didn't notice until I was running down the irregular surfaces of the Chumash Trail is how the XT Hawk 2's combination of flexibility, support and cushioning combine to produce a really comfortable ride. Based on the shoe's performance on the Bandit's tough 19.5 mile course, I'm looking forward to trying the shoe on some longer mountain runs or races.

Trail runners, do you suffer the embarrassment of continually being passed on hills? Legs aren't what they used to be? You need the new Hill Climbing Helper®.

The Hill Climbing Helper's portability is the key! The Hill Climbing Helper® may look heavy, and it is, but that's part of the genius of its design.

• Can be used on all your favorite trail runs!
• Fits most hills!
• More effective than elliptical or stair-climbing machines!
• Increases safety. Eliminates fear of slipping or falling.

Includes 10 stairs and 2 hand rails. Constructed of the finest oil field steel - it will last for decades!

You'll notice the HCH difference on your first run!

At one time or another, most of us have run barefoot -- on a beach or in a park, or certainly somewhere as a child.

As a result of the insight and enthusiasm of Barefoot Ted McDonald, and the publication of Christopher McDougall's book Born to Run, runners have been swept into a new era of minimalist running using Vibram FiveFingers (VFFs). Now a runner can, with VFFs and a little care, run trails virtually barefoot.

"What's the elevation gain?" is a common question when talking about a trail run, because it makes such a huge difference in the difficulty of the run. All the technology we have for recording and analyzing trail runs is remarkable, but it can sometimes produce misleading and wildly inaccurate results. This is particularly the case when using a GPS track to calculate elevation gain and loss.

Last Sunday's trail run in the San Gabriel Mountains is a good example. The course started at Islip Saddle, dropped down to South Fork Campground, climbed to the summit of Mt. Baden-Powell by way of Vincent Gap, and then returned on the PCT to Islip Saddle. The GPS track was recorded on a Garmin Forerunner 205. So what was the elevation gain on the loop?

According to Garmin Training Center, the gain was about 10,500'. The same track in TOPO! calculated the gain at about 6,100'. SportTracks, using corrected SRTM-based elevations and moderate smoothing, came up with 5800'. When uploaded to Garmin Connect, the track produced a fanciful elevation gain of about 13,600'!

Last year I used a Polar 625X on this course. It measures elevation gain/loss based on changes in barometric pressure, and came up with a gain of 5400'. So which of these values is the closest to reality?

Fortunately, in the case of elevation gain/loss it's fairly easy to do a low tech sanity check of these high tech results. All that is required is to get out a topo map, either electronically or on paper, and do a little arithmetic.

In the case of Sunday's loop, the gain from South Fork Campground to the summit of Baden-Powell is about 4830'. The gain on the PCT up and over the shoulder of Throop Peak is about 375'. A couple of other minor climbs total 240'. This gives a total of 5445'. Adding in a fudge factor of 200' for very small climbs that were not included in the total, the result is a reality checked gain of about 5645'.

The title photograph is from a run on the Hummingbird Trail yesterday.

Note: A long-standing rule of thumb, Naismiths Rule, says that the additional time required to gain 1000 ft. on a run/hike, will be the same as the the time to run/hike 1.5 miles on the flat. See "Short and hilly or long and flat?" in the Mountaineering Council of Scotland's The SCOTTISH MOUNTAINEER (Issue 7, March 2001).

The trail shoes I've been running in the most over the last several months are the Salomon XT Wings, Salomon SpeedComp, and the adidas Response Trail 15. I've been happy with the performance of these shoes, but still like to try something new from time to time.

Recently, the cushioning on one of my pairs of XT Wings died, so I thought I'd give the Montrail Mountain Masochist a try. I've now run about 35 miles in the Mountain Masochist, on a variety of courses, including the Mt. Pinos trail run on Sunday. Trail surfaces have ranged from smooth dirt road to very rocky, technical single track trail.

From the first mile the shoes have been comfortable, and fit my moderately high-arched, D-width foot well. At 12 oz./each (US size 9.5) are on the lighter side for a medium weight shoe.

The outsole appeared to have good traction on a mix of dry surfaces without being overly aggressive and grabby. On the rocky sections of trail, the shield in the midsole did a good job of protecting against pointy rocks.

My foot likes a neutral shoe with little or no pronation control, and so far the modest amount of pronation control in the Mountain Masochist has not felt overly restrictive. (See update below.)

The shoe seems to encourage a more forward body position and foot strike, which I prefer. The forefoot cushioning is good, and the strike-to-toe transitions feel smooth. On rough trails, the shoe has been stable, and I have not noticed any abnormal tendency to roll an ankle.

Overall, the Mountain Masochist appears to be a balanced, well thought out design. I hope to get them out on a 20+ mile mountain run soon.

Update 08/05/09. I now have 81 miles on this shoe and used it on the Cottonwood - New Army Pass loop in the Sierra back in July. Overall, the shoe has performed well. I do notice the pronation control on longer runs, and would love to see a version of this shoe designed for a neutral foot.

A search on the phrases "stride rate" or "running cadence" will turn up numerous articles extolling the benefits of a running cadence (stride rate) in the neighborhood of 90. An often quoted source of this axiom is Daniels' Running Formula: Proven Programs: 800 M to the Marathon (Human Kinetics, 2004). The idea is that for a given speed, the faster your stride rate, the less time your body will spend airborne, the less you displace your center of mass, and the softer you hit the ground on landing. Less up and down should translate to more energy efficient running.

Comfortable, cushioned and durable. That's how I would characterize the adidas Response Trail. I've had two pairs of the Response Trail 14s in my shoe rotation since September 2007, and logged around 1000 miles between them. (Your mileage may vary.)

About a month ago I replaced one of the pairs with the adidas Response Trail 15s. I've put 75 miles on the new pair, and other than a change in colors, it seems not much has changed in the shoe. It's still well-cushioned, comfortable and lightweight. The new pair weighed in at 24.7 oz./pair (US 9.5). At $80 or less, the Response Trail 15s are an excellent value.

At the moment, my primary trail running shoes are the Salomon XT Wings (105 miles), Salomon SpeedComp (110 miles), and adidas Response Trail 15s.

A sib of the ultralight SpeedCross 2, the Salomon SpeedComp trail running shoe trades the "snow and mud rated" lug sole of the SpeedCross 2 for a high traction tread reminiscent of a low profile, high performance tire. The result is a fast, lightweight shoe that should perform well on most trails and in a variety of conditions.

Mine arrived yesterday and I took them out for a 7 mile spin at Ahmanson Ranch. There were no surprises -- the SpeedComp ran very similar to the SpeedCross 2, with good shock absorption and cushioning for such a lightweight shoe.

In addition to the outsole tread, there are a few other differences in design. The toe cap of the SpeedComp extends further back along the welt, and the sole wraps up over the sides of the cap, providing additional protection on rocky trails. A heel pull-tab has also been added.

My pair of SpeedComps (US 9.0) weighed in at a light 22.6 oz.

Update 05/29/09. In rotation with two pairs of XT Wings, and a pair of Adidas Response Trail 15s, I've now logged 235 miles on the Speedcomps, and have not changed my opinion of the shoe. I used the Speedcomps in the Boney Mountain Half Marathon, Bandit 30K, and Malibu Creek Challenge 22K, with excellent results -- two firsts and a second in my age class.

Update 01/29/09. In rotation with my other shoes, I've logged 150 miles in the Speedcomps now. I've used them on a variety of trails and terrain, and am very happy with the shoe.

Update 09/21/08. Did the 14 mile Bulldog Loop in the SpeedComps today. This course is mostly ungroomed dirt road, but there is also some rocky single track, a section on exposed sandstone, and even a little pavement. The SpeedComp was comfortable, nimble, and it's traction on the rocky sections was impressive.

Introduced around 2000, the Garmin eTrex was the first GPS unit I used to trace a trail run. The GPS tracks were imported into TOPO! where the length of a run could be measured, an elevation profile generated, and the topography of the run examined.

Since the eTrex was designed to be used in an "orienteering" position -- flat in your hand in front of your body -- it would frequently have trouble receiving GPS satellite signals if hand-carried while running or hiking. About the time enterprising hikers and runners began to resolve this issue with creative hats, holsters and harnesses, Garmin released the Forerunner 201, greatly simplifying the task of tracing a route.

In 2005, while preparing a presentation about kayaking Piru Creek for a meeting with the Forest Service, I stumbled onto Keyhole.com. To say I was blown away by this bit of "Eureka" technology would be an a gross understatement. Now, in addition to seeing Piru Creek in photographs, and on a topo map, you could get a "before you paddle" preview using Keyhole -- even if you couldn't paddle class IV whitewater! Google acquired Keyhole in late 2004 and launched Google Earth on June 28, 2005.

Shortly after Google Earth was launched, SportTracks added the ability to launch Google Earth and view the GPS trace of a run or other activity. Since SportTracks could also directly import data from Garmin's Forerunner, the software made it very easy to view a run in Google Earth.

I've been working on updating the posts on Photography on the Run that reference a trail run to include a link to a Google Earth KMZ file. A KMZ file is just a zipped KML file, and either can be opened in Google Earth. A list of the trail runs with KMZ file links can be found by clicking "Google Earth KMZ Files of Trail Runs" in the sidebar.

These are actual tracks recorded by a GPS during a trail run and may contain GPS errors, route-finding errors, and wanderings that are difficult to explain. In a few instances tracks have been modified to correct errors, or to remove side excursions that are not part of the usual route, but not all errors have been corrected. No claim is being made regarding the appropriateness or suitability of the routes indicated. The GPS devices used to record these tracks include the Garmin Forerunner 201, Foretrex 201 and Forerunner 205; and the GlobalSat GH-615B.

Ounces count when you're fighting gravity -- in your pack, on your body, and especially on your feet.

The Salomon SpeedCross 2 (left) and adidas Response Trail 14 are my two lightest trail running shoes. My Response Trail 14's weigh 24.2 oz./pair (US 9.5), and the SpeedCross 2's weigh 21.3 oz./pair (US 9.0).

Last updated 07/05/10. Symmetrical lacing and new eyelets working great on XT Wings 2!

Wow -- what a great ride! That was my impression the first time I used the Salomon XT Wings trail running shoes. That continues to be my feeling after using the shoe for a couple of weeks and doing several runs in the 15-20 mile range. For my particular trail running requirements, this shoe has a near perfect balance of comfort, smooth ride, cushioning, traction and support.
