Pike's Peak Ascent.
We did it! Our initial goal was to make it under the cutoff time of 6:30, which we revised downward to 6 hours (didn't want to aim just for the cutoff and then be a minute late!). Then after a training hike on the lower 2000 vertical feet of the course, we revised our goal downward to 5:30. So finishing in 5:18 was very gratifying.
More details (way too long I realize, but it's tough to describe how the race went without giving some background of the course):
The Pike's Peak Ascent, which covers 13.3 miles and has a vertical gain of 7800 feet (ending at 14,000 feet), is a long, relentless uphill, but for the most part, is not super steep. The average grade is 11%, nothing to be sneezed at, but not like heading up a black diamond ski slope, for example.
For reference, some grades of hills around here: The Empire Blvd hill from the bottom (at the bay) heading west is 5%. The Glen Edith hill (from Bay and Ridge in Webster, down to the bay) is 7%. Smith Road, in Irondequoit Bay Park East, from the cul de sac down to the bay, is 8%. At Bristol Mountain, where we did some training hikes, if you go up the hills that represent the easiest way down from the top (the "Green" slopes), it comes out to almost exactly 11%, same as Pike's Peak. Still, at my level of fitness, I find I can't run any appreciable distance on an 11% grade.
Because of the uphill grade and the altitude, one of the first things regarding the Pike's Peak Ascent is that the any normal frames of reference in terms of "minutes per mile" (or minutes per km) can be thrown out the window. Both in terms of the average pace for the whole race, and also within the race, as in general, each mile is tougher than the mile before it.
To elaborate, with some examples: This year's men's winner, Matt Carpenter (who has run a flatland marathon in 2:32 and a 10K in 31 minutes), averaged 10 minutes per mile in the Ascent. Averaging 15 minutes per mile would put one in the top 10% of the men, and averaging 16:45 per mile would put one in the top 10% of the ladies.
Also, in terms of pace per mile changes within the race, a male at the 10th percentile (15 minutes per mile) would be expected to run the first 1.25 miles of the course at around 10 minutes per mile, but the last mile of the course (which climbs 770 feet, for a grade of 14.6%, ending at 14,000 feet) in more than 20 minutes.
Fortunately, there is a pace chart that has been created that will tell you what your time should be at various key points (9 different places) in the race, for a given finish time. Using this chart, at any of these particular places, you can tell that, for example, you're on schedule for a 4 hour time, or a 5 hour time, etc.
A drawback of this pace chart is that it is assuming that one has done significant training at high altitude (10,000 to 12,000 feet) and at very high altitude (12,000 to 14,000 feet). For flatlanders like Anne and me, the pace chart warned that our pace in the upper part of the course would take a substantial hit, due to the altitude. This would say that, for example, if we thought we were capable of a 5:30 time, our pace on the lower part of the mountain should be somewhat faster than a 5:30 pace, knowing that our pace would be slower than a 5:30 pace on the upper part. The big warning that came with this information is to NOT go out too fast, that the pace on the lower part still needs to feel very relaxed, otherwise, really bad things will happen as the altitude increases.
So we decided to aim for a 5:30 finish time, which was based on a training hike we did on the bottom 2000 vertical feet, where we didn't think we were pushing the pace all that much and still did splits that had us on track for a 5 hour finish. (And taking into account that we would slow down at higher altitudes.)
On the day of the race, we fortunately fell in with a group that was going at just about the right pace for us on the lower part of the course, where it is difficult to do any passing. We hit our split time at the "Top of the W's" (about 20% into the course) on a slightly better than 5-hour pace. Without boring you with excessive detail about split times, things went according to plan: we kept up the 5-hour pace for the next couple of splits, then we started to slow down at the altitude became more of a factor, which was expected, but we didn't slow down all that much. For the most part, our intermediate split times between various milestones never got below a 5:30 pace.
I kept fearing that we'd do the equivalent of hitting the wall in a marathon, but that never happened. The altitude didn't get to me in a significant way until approximately the top 1000 vertical feet of the course, from 13,000 feet upwards. By that point, I could tell that our pace was quite slow, but the important thing was that we were able to keep moving.
Words of advice from a number of people who had done this before were:
Keep moving, no matter how slow;
and: NEVER EVER sit down. ("No matter how inviting that rock looks, don't sit down on it" was one person's wording.)
We probably passed around 50 people sitting down above the tree line. Not many looked like they were in major distress, but most kind of looked dazed and expressionless. In most cases, I'm sure this was a result of them going out too fast at the beginning of the race, something that we managed to avoid doing.
The last third of a mile of the course was particularly tough, as it climbs around 320 feet (18% grade!), and at that level of fatigue, and with that little oxygen in the air, it was a major challenge. But the finish line was visible (although it looked VERY high up), with the PA announcer calling out people's names and hometowns as they approached the finish, so it wasn't hard to muster up the enthusiasm and energy to make it up that brutal hill.
Anne and I did the whole race together, sometimes being a bit apart when a few people were between us in the single track, but finishing less than a second apart. I'm quite a bit faster than her in any sort of flat races, but this was more of a strenuous hike than a running race, and she and I are pretty equal when it comes to hiking. She was a bit concerned that she would hold me up, and she told me before the race that I should feel free to go faster if I could, but frankly, I don't think I could have done it that much faster than we did, without feeling I was risking blowing the whole thing by burning out too quickly. It was definitely nice doing the race together, after working together on training runs/hikes for so many months.
We were very lucky in terms of the weather. It was sunny and 70 at the start of the race, and sunny and around 50 at the summit, with only moderate winds (forecasts of 40+ mph winds didn't materialize, fortunately). The view from the top, after having completed the exhausting climb, was something I wouldn't trade for anything.
A major surprise is that we felt great after the race, both that day and the next day. Way better than after a marathon, for example. My theory: We were so limited by our heart and lung capacity, that our legs really didn't get the workout they would have at lower elevations.
