The skinny: 20 miles in 4:59:18, with the final 4 miles (W. Peoria Heading course) being done in 58:49. I also added 6:14 in case my course was short (I sort of winged part of it) to get 5:05:32 for 20.4 miles.
Weather: overcast with periods of sun; 66 F with 65 percent humidity at the start; 80 F with 52 percent humidity at the finish; I beat the cold front with rain by about 10 minutes.
I did my best walking in the final hour; that might be because that was the flat part of the course.
For Peoria types:
Cooper to Laura (onto the BU campus) to Maplewood to Columbia Terrace. Then to Broadway all the way to McClure. Then to Bootz, Corrington, Bigelow to Forrest Hill (turn right). Take that to Central, go north to Peoria Heights (Marietta) to Prospect to Tower Park. Pit stop.
Then to Grandview, to East Grandview Dr., Harmon, Bishop Hill where I took the Rock Island trail (bikepath) all the way past Affina into Springdale Cemetery. Then to the bottom of Glenn Oak Park, up the hill, around the Park District Building, through the new parking lot along the sidewalk; exit, turn north on Prospect, turn left (West) on Forrest Hill….retrace the out part except when I got to Columbia Terrace, I kept going all the way to Parkside.
Then along Main/Western and turn onto Heading and go until it runs out. Then left, right to Swords, left, first left then down a few blocks and turn right to get to Rohmann, right on Sterling past the Cemetery and right on Kickapoo..through the brick street neighborhoods to Manor Parkway by the golf course..then to Waverly all the way to Rohmann then right to Western then right on Bradley ave. to Cooper.
It was a bit of everything; I saw other people on the course.
While it was my best long walk of the year and my best week since October 2014, it still wasn’t much. I have to be aware of that.
Along the way, I heard a call of a green frog (Rana Clamitans)
Can you spot the frogs? Clicking the link will take you Mathew Cobb’s post at Why Evolution is True (photo by Nash Turley)
I’m sure that you can, but this photo shows what evolutionary adaptation can do.
Also, WEIT provided a link to this little gem: these “rotating dots” are, individually, moving along a straight line path. Seriously…all of them are.
I am going to try to write some equations that describe this motion.
I wasn’t sure as to what course I wanted to do, so I found myself heading down the bluff toward the river trail. But my initial pace was painfully slow! It took me 16 minutes to do the first 1.03 miles (along Moss Avenue). So I knew that somewhere I’d need to put in some “pick ups” to get within shouting distance of a marathon race pace.
So I walked down the trail and up to the old Woodruff track (5.17 miles), did 32 laps on the track (mostly right on the outside line of lane 1 as it is a 400 meter track) and then walked back.
Times: 1:17:35 for the first 5.17 miles
1:50:07 for 8 track miles (3:07:42)
4:24:40 for 18.35
2 mile segment times: 27:48, 27:37, 27:23, 27:16 track
This walk: I had to stretch my back (McKenzie exercises) prior to getting out there. Also this weird weather has been playing havoc with my left knee. But I had no problems while out there.
It was drizzling (lightly) at the start. The out and back were the easiest parts; the stuff on the track was the toughest stretch. I kept telling myself “I goat this”. The final stretch was easier than I had feared it would be; note the “back” stretch is net uphill so it is good that it was a tiny bit faster than the outstretch.
This is my 5’th walk of over 17 miles in my build up. The marathon is 6 weeks away; that gives me 4 training weeks left. One week will feature a parent’s weekend trip to see my daughter, and one will feature a hilly half marathon; I might have to get in an easy 4 miles prior to that.
So my plan:
24 August: 20 or bust.
31 August: lift/swim (4 mile race on Monday), 2 September (Tuesday): 4 hours in the morning.
7 September: half marathon with extra (17 total)
14 September: Parent’s weekend. 16 September (Tuesday) : 4 hours on the morning.
I’ll have MP walks (10 miles) at pace on Wednesdays when I don’t have a long walk on Tuesday.
Reptiles and Amphibians: Barbara and I usually eat Indian lunch on Sundays. Afterward, we went to a Reptile/Amphibian exhibition. I think that the African Bullfrog stole the show. It is one of those frogs that sure looks like a toad. There were some geckos and other iguanas, turtles, and yes, snakes.
Scientists figure out a bit about a toad’s brain (observation, hypothesis, experiment, model, predction)
First a bonus: Jerry Coyne’s website has a post about mayfly emergence showing up on radar!
Toad Brain Activity
A friend alerted me to this post, which is about how a toad reacts to stimuli which mimics prey in the wild. There was a bit of a “ha, ha, watch the stupid toad get “owned”” but the videos are quite interesting and illuminate how science works.
First, there is the observation (toad hunting a worm).
(photo: Heidi Carpenter)
Then some conjectures are made: “what type of stimuli elicits a “hunt” response”?
Then there is an series of “experiment followed by a refined conjecture”; here we see what “looks like” prey to the toad and what doesn’t, and what sort of response does the toad make? Then we look at the signals in the toad’s brain.
It turns out that there are a couple of receptors involved: one if the “predator” sensor is activated, it sends a signal which cancels the “hunt maneuver” response. How is this verified: one can disconnect the “canceling signal” pathway.
Then the whole lot is modeled by a neural network which elicits the predicted response. Yes, there is some mathematics that underlies this, which includes signal theory, neural networks, probability and possibly fuzzy set theory as the “predator/prey” sets appear to be fuzzy.
The videos total 30 minutes but are worth watching.
Exercise There is some evidence that exercise can clear unnecessary stuff in the short term memory. Tests on mice have shown that treadmill running helps them forget electric shocks. But there is more in this article:
Adult mice that exercised on a running wheel after experiencing an event were more likely than their inactive mates to forget the experience, according to a paper from researchers at the University of Toronto, published in Science today (May 8). The results suggest that the production of new neurons—neurogenesis—prompted by the exercise wiped out the mice’s memories. They might also explain why human infants, whose brains exhibit abundant neurogenesis, do not have long-term memories.
“In general, hippocampal neurogenesis has been thought to be the basis for memory and they’re suggesting that it’s the basis for amnesia,” said Thomas Insel, director of the National Institute of Mental Health. “That’s a very controversial and provocative concept.”
Infantile amnesia is common to all humans. Children typically do not develop long-term memories until age three or four. But why is that? Sheena Josselyn and her husband Paul Frankland, who are both neuroscientists at the University of Toronto, pondered precisely that question after noticing that their two-year-old daughter could easily remember things that happened within a day or two, but not several months in the past.
More specifically, they wondered whether it might have something to do with neurogenesis in the hippocampus—a brain region involved in learning and memory. Hippocampal neurons are produced rapidly during infancy, but neuronal generation in the region slows to a trickle in adulthood. “This inverse relationship between the levels of neurogenesis and the ability to form a long-term memory got us thinking that maybe one is due to the other,” said Josselyn.

Government intervention and fisheries: Via Paul Krugman:
Brad Plumer tells an important, little-known tale. It begins with things going badly:
Back in the 1980s and ’90s, many fisheries in the US were in serious trouble. Fish populations were dropping sharply. Some of New England’s best-known groundfish stocks — including flounder, cod, and haddock — had collapsed, costing the region’s coastal communities hundreds of millions of dollars.
So the government got involved. But we know that government is always the problem, never the solution; so you know what came next.
Or maybe you don’t. In fact, government intervention has been a big success. Many fisheries have rebounded, to the benefit of the fishermen as well as consumers.
Fighting climate change isn’t really all that different from saving fisheries; if we ever get around to doing the obvious, it will be easier and more successful than anyone now expects.
There are types of frogs whose males dance to attract mates (surf to the page to see the video) but, unfortunately, these frogs are endangered. These are small, walnut size frogs.
Animals of Chernobyl
Since background radiation is too high for humans to live there, the exclusion zone around Chernobyl is like a wild habitat. So, scientists are seeing some interesting developments in the animals of the region.
GMO issues Here is a guide to looking at some of the anti-GMO stuff that is out there.
I watched our university women’s team lose at home, then watched our men’s team lose in the “play in” round in the Missouri Valley Conference tournament.
So, I slept in an extra hour and went to morning swim: I did that “fresh” (without lifting first):
2 x 250 warm up 500’s (on the 5)
10 x 100 on the 2:05 (1:45-1:48 each; couldn’t go faster)
100 in 1:45 (oh well)
4 x 25 fist, 25 free on 1:05
3 x 50 fly (fins)
25 fly, 25 free.
Then after my 9-10 class, I got in about a 1 hour weight workout. Full weights; my bench suffered:
rotator cuff, Achilles, hip hikes
pull ups: 5 sets of 10 (ok)
bench (weak) 10 x 135, 1 x 180, 7 x 160, 7 x 160
super set: 3 sets of (12 x 50 dumbbell military), 10 x 25 dumbbell upright row, 10 x 30 dumbbell curl.
super set: 3 sets of 10 (pull downs: 160, Hammer Machine Row: 210, 210, 200).
That was it.
Today: busy with candidate stuff and a couple of quizzes.
Someone said this was about me:
And this is funny (and fun)
The upshot: these frogs only have a brief window in which to mate; hence they are out, even when it is cold. And they can stay in amplexus for months (the fertilization takes place outside of the body; the female releases the eggs and the male fertilizes them):
Though egg laying takes place in spring, frog pairs in mountain ponds can begin hibernation in amplexus—a months-long embrace that may provide a breeding advantage by allowing mating as quickly as possible once warm weather arrives. Eggs of high-elevation frogs may be 30 percent larger than those of lowland females, giving tadpoles a head start. Eggs and tadpoles of mountain frogs have developed resistance to genetic damage from ultraviolet radiation, a component of sunlight that is more intense in the thinner air of high altitude.
And yes, frogs (at least many of them) have a type of antifreeze to protect against frostbite and to keep the vital organs alive.
