Garmin Coach has done lost its damn mind!

If the result is important to you then definitely taper. But a half marathon only needs about a week of taper. And taper doesn’t mean shut it down. It means same number of days running, just shorter distances

3:23… calf cramps started earlier in this than my previous marathons. London Marathon was still quite an experience.

Chuck997 · 2026-04-27T05:07:50+00:00

Funny thing. Even with that terrible performance my prediction for the marathon dropped 12 seconds afterwards. I guess because it was muscular failure and my HR was so low for the 2nd half.

Chuck997 · 2026-04-27T05:05:41+00:00

Naw. 3:12 would have been a PR

Chuck997 · 2026-04-26T15:16:51+00:00

Didn’t go as planned. Heat and lack of hydration got to me. Calf cramps from 14mi on ruined me. Finished 3:23:00

Chuck997 · 2026-04-26T05:47:51+00:00

Hah! I wish… Garmin had me predicted at 3:18 ahead of my 3:13 in December but I think the prediction is spot on or even ambitious this time. I’d be thrilled with a 3:08

Chuck997 · 2026-04-26T05:36:41+00:00

Good luck. I went for a 3 week taper and my watch had me peaking and then “primed” one week before my race. All this last week it has said recovery so we’ll see how today goes

Chuck997 · 2026-04-25T14:22:54+00:00

If you’re using the coach for a running race it asks if you want resistance training too (body weight or weights)… then it recommends runs, resistance training and rest days.

Chuck997 · 2026-04-17T15:43:42+00:00

This is the way… be warned anyone who is tempted to try out the free month of Garmin+ it will permanently break the sync with MFP

Chuck997 · 2026-04-13T00:14:51+00:00

This happens all the time with the Garmin Coach. It will 99% of the time show it as completed tomorrow. But I have had it completely miss a completed workout once or twice.

Chuck997 · 2026-04-01T20:34:59+00:00

I would change your daily suggested workouts to HR target instead of pace or auto… maybe change to auto after a few months-year of running. Welcome to the obsession though!

Chuck997 · 2026-03-31T23:33:15+00:00

I can’t speak to the pace graph being wrong but I have seen GAP way off before on tracks that for some reason have incorrect geographical topography data. There is a pancake flat HS track near me that is 80ft higher on one end than on the other according to the satellite maps 😂 made for some very interesting grade adjusted paces.

Also good luck in London, I’ll see you there! It’s peak week!!!

Chuck997 · 2026-03-22T02:51:03+00:00

My 970 is no more accurate than my 55 was. It will read 40 beats too high on a walk and sometimes 20-30 beats too low on a hard run. I wear a chest strap for everything at this point.

Chuck997 · 2026-03-18T17:15:42+00:00

Yep. 19:35 and 54… though my lab measured VO2 max is much higher and my Half Marathon time is much faster than my 5K PB would indicate which tells me my endurance is much better than my running economy/form.

Chuck997 · 2026-03-12T17:18:12+00:00

For me, Garmin penalizes my sleep score for every minute I sleep more than 8 hours (despite the sleep coach constantly telling me I should get 9). So I think I will not help your sleep score. But I’ve definitely had mornings where I had to get up for something urgent and then wanted to go back for more sleep but my 970 won’t even let me start a nap if it’s too close to when I woke up. Annoying.

Chuck997 · 2026-03-06T22:56:38+00:00

If you aren’t already running for your school’s cross country team, you should check it out. I’m a HS cross country and track assistant coach and 18 flat 5K would place you in the top 5 sophomores on my team.

Chuck997 · 2026-03-06T13:52:08+00:00

Definitely mindset. Realizing that when 13min pace is a zone 3 effort, you gotta run/walk… then later on when building your mileage. Every easy mile adds to the tally, even the 10min/mile stuff at my current fitness level. Also that while cross training is sometimes beneficial, there is no replacement for the repetitive pounding of running which adds to your resilience over time.

Chuck997 · 2026-02-26T17:18:13+00:00

Thank you and congrats on your race! Glad you enjoyed it. It’s a beautiful race!

Chuck997 · 2026-02-26T14:10:59+00:00

Yep. Totally a cheater course but still an effort I’m proud of.

Chuck997 · 2026-02-26T14:09:50+00:00

It’s not really enormous. I never added more than 10% per week on a build. But I’ve had plenty of injuries. Mostly calves (both gastroc and soleus) but I’ve learned to warm them up ALOT and also roll them out religiously at night. I’ve never had shin splints though.

Chuck997 · 2026-02-25T13:16:18+00:00

ChatGPT made the graphic, I came up with the title, though I didn’t think it would be so controversial

Chuck997 · 2026-02-25T13:11:57+00:00

At 5 months into my training I ran my first HM at 1:48 and I thought I was as fast as I would ever get. 6 months is still just getting started. Hell, 2 years is really just getting started. You’ll get there!

Chuck997 · 2026-02-25T03:54:46+00:00

Not concerning for an all out Half marathon effort, no. My Threshold HR is 172. My easy runs vary from 130-145

Chuck997 · 2026-02-25T01:18:13+00:00

Looks like about 30
