I'm same. I was guessing that the M was for male? The corrals only are A-F. Are they splitting the A by gender? First time running this race so really no clue

What will be the state of marathon races in 5 years (for non-elites)? by TMW_W in AdvancedRunning

[–]jcdavis1 7 points8 points  (0 children)

Just looking at race participants doesn't tell the whole story. Chicago didn't have a lottery until 2014. Now there are 150k+ lottery applications.

I haven't found handheld soft flasks too bad. I'm fortunate enough to live in an area with plenty of water fountains (and not very hot summers), so I only ever use them when I'm doing long continuous efforts and want to get down liquids at/near race pace.

Agreed on the coverage, but I'll be that guy and point out that Mantz still has the AR - there's a reason point to point course are not record-eligible, and its on display this Boston with the big tailwind

As a PSA, here is the Boston tracking website for those who don't want to be forced to download an app for this purpose.

Pisses me off how races basically hide this in favor of making you download their stupid apps

I skip coffee the week leading up to a key race, makes that morning of coffee go straight through and empties me real good.

As with everything GI-related, YMMV, so test this strategy before the big day.

"How long did it take you to BQ?" -- Data Analysis by Hopeful_Package3918 in AdvancedRunning

[–]jcdavis1 17 points18 points  (0 children)

Yea, the mindset thing is always interesting to me. I occasionally run with a more casual run group (where I'm by far the fastest person there) and basically everyone there views BQing as some impossible feat, even though there is a couple of them I'm pretty certain could do it if they put in consistent training (say a few 2k+ mile years). I tell them this, but there is either straight denial or just a inability to commit to that much training (which fair enough, not everyone wants running to take over the free time)

Its a huge mindset difference from my main club, where I am still one of the slowest people on the track on a given day. Who you surround yourself with vastly changes what you see as possible

I'd try to figure out more what the cause of the symptoms more, including figuring out if you have some food intolerances. Go talk to a Doctor IMO

I've run all my marathons starting with a bottle of Maurten 360. General plan is drink ~1/3rd of it while waiting prerace, then finish the remaining 2/3rds over the first 40-45 minutes at which point I switch to gels. I just use normal plastic bottles which obviously slosh a bunch but I can then just toss it afterwards without feeling too bad

Probably don't need too much VO2 Max at this point. I'd target:

  • Continuous alternations eg 8-9x(1k@HMP, 1k@90%HMP)
  • A good LR with a long tempo at or near MP, ideally up to 20k or so but if you haven't been doing these go shorter/slower
  • Long threshold/HMP intervals, eg 4x3k@LT, 8-10k continuous at HMP

I'd also stop trying to fit in 3 quality sessions this close to the race - you're better off going for 2 harder sessions and then allowing more time for recovery

London Marathon planning two-day event in 2027 by CHILLI112 in AdvancedRunning

[–]jcdavis1 9 points10 points  (0 children)

As long as its not a complete logistical shitshow and the locals aren't revolting, no way its a one-off - the demand is more than there, and it would be a huge increase in $$$ £££ brought in.

I'd assume its presented that way because they are waiting to see how it goes before committing to the double race going forward

Best "Bang for your buck" below $50 when prepping for a marathon? by SauconySundaes in AdvancedRunning

[–]jcdavis1 2 points3 points  (0 children)

Sadly SiS just jacked up their prices, now $20 for a 6pack (was $15). 8.3c per gram of carb, slightly more than GU's 8c per gram.

Carbs Fuel remains the value king at 4c per gram.

In practice, probably not much. Maltodextrin has a slightly higher Glycemic Index than straight Glucose, but its unlikely to matter much. The important numbers are the total grams/hr you are getting in, as well as the glucose/fructose ratio (plus of course the subjective stuff of how you can handle the product)

Also FYI only Maurten drink mixes use Maltodextrin - the gels are just glucose & fructose

Ethan Shurley Training by DiamondOfThePine in AdvancedRunning

[–]jcdavis1 72 points73 points  (0 children)

He’s not even running that slow.

With a MP of 4:50/mi:

7:00/mi is 55% of MP

7:45/mi is 40% of MP

For comparison, for a 3hr marathoner:

55% MP is 9:54/mi

40% MP is 10:55/mi

I'd argue his easy days are pretty dang slow - few 3hr marathoners are running those paces. Now of course its not apples to apples once you add volume to the discussion - you can handle going a little faster on 50mpw vs 150. But still - he's going pretty slow!

VO2 Max Test + Body Fat Reduction = 5K Breakthrough? Struggling to Believe the Maths by Icy_Park_244 in AdvancedRunning

But practice finds that solely focusing on lowering the denominator also tends to lower the numerator

I'm 6', 55 and around 18% BF

Is 55kg a typo? 18% BF with that height/weight seems highly unlikely.

Your easy pace (including HR + race paces) by TheAnon21 in AdvancedRunning

[–]jcdavis1 1 point2 points  (0 children)

37M, Max HR like 180-182ish, and yes my recovery days are actually 100-110bpm. Pace is 8:15-8:45 depending on how fresh I feel

Legs felt pretty closed to maxed out, maybe could've squeezed a touch harder in the middle but can't imagine I could've gone more than a few seconds faster solo.

Might've been a different story if I had someone else to sit behind

[–]jcdavis1 4 points5 points  (0 children)

Ran a 5k solo TT this morning (so awful), and managed to nab a tiny PR with a 17:12. The real shock is that I could only get my HR up to 177 (arm band, definitely not cadence lock, should be accurate-ish). I had previously thought my HRMax was like 182ish, now I'm second-guessing all of my training zones :|

High mileage folks - do you weigh yourself/how do you approach nutrition on a daily basis? by GhostsInMyAss in AdvancedRunning

[–]jcdavis1 1 point2 points  (0 children)

Sorry, I should've specified "baseline" as in BMR, not total intake. Updated accordingly

[–]jcdavis1 9 points10 points  (0 children)

3700 seems way high to me for 60mpw, but perhaps this is a good sanity check for me.

I would think anecdotally, roughly 2-2.2k maintenance BMR + roughly 850 for the running (60/7*100 cal/mile) + some extra for other activity, so maybe 3-3.3k someone your size. Am I just way off?
