`
`I'm not trying to brag, but my Cardio Fitness score seems way too high.
`
`| started running two months ago, and | could orly run for a mile and half before being exhausted.
`
`| knew
`
`| had to build endurance.
`
`In the beginning of this month | bought the Charge 2 to really track my
`
`progress, and | discover the app has a cardio fitness score. My score is already above 55, excellent for a
`
`man of my age. Howis it so high when | was never really athletic until two months ago? Also, | can now
`run 3.4 miles for 30 minutes.

`
`online.
`
`It will help you avoid injury, and continue your progression if you so desire.
`
`Hal Higdon is a source | always use. For brand new runners | always recommend the 30-30 Plan or one
`
`of the 5K training programs. But you seemed to have progressed beyond that already, so maybe a 10K
`
`training plan? You don't even haveto betraining for an actual race if you don't want to,it could just be a
`
`good way to work up to running 6.2 miles safely.
`
`I'm not sureif links work here, I'm going to try to link you to Hal Higdon's 10k Novice plan. (He has free
`
`plans and interactive plans which you haveto payfor,I've always found the free plans just fine.)
`
`If the link
`
`doesn't work,just Google Hal Higdon and click training plans. Good luck!

`
`It seems resting heart rate is also a factor, mine is around 56-58bpm according to mytracker.

`Your 8min/mile 12k sounds impressive to me. | hope to achieve that endurance in a few months.

`Interesting. | had the opposite. | am 40 and have run outdoors for most of mylife. When | got mine | was in
`
`the low 'good! range and remained there for the few months I've had mine.| eat well and exercise every
`
`day with at least every other day being a run. Running is relaxing for me. Cardio | can do, just not winning
`
`any lifting competitions.
`
`This is week | find myself in a hotel with tornados and high wind so | turned to the treadmill. | was
`
`watching the newsas | did this so | just did a 2 mile run at 18 mins. When | finished the Fitbit read it as .78
`
`miles in 18 mins and my score droppedall the way to mid ‘fair’
`
`| don't Know the calculation that goesinto this, but for it to never improve and then drop 2 whole levels
`
`after one poorly recorded run was disappointing.
`
`| love the Fitbit, but disappointed in this area.
`
`Congrats on on getting out there and your impressive improvements.

`
`| recommend checking your stride length settings on your Fitbit. Running outdoors with GPS to map out
`
`your distance is more accurate than running in one placeif your stride length isn't set properly. | don't
`
`expect the cardio scores to be real indicators of health. It's better to judge on how well you are by
`
`improved running, working out, and regular physicals from a doctor.

`3.4 miles in 30 minutes is not bad at all (it’s almost 11 km/h). You may want to perform the Cooper’s test

`
`There’s an app called Fitdigits you can use to perform Cooper's test. Also see this Wikipedia article.
`
`| also found Fitbit’s cardio fitness score to be higher than what | got with Cooper (though | performed the
`
`test 3.5 years ago and I’ve probably improved my cardio fitness a bit since).

`
`My Fitbit VO2Max number is definitely genetically affected.. I'm 77 and have a Fitbit cardio Fitness of 42-
`
`46.. It was 43-47 but my RHR has gone from 51-55 overthe last few weeks.. Probably affected by
`
`vaccination shots for Flu, Pheumonia and Shingles. Never had the shots before. Also need more blankets
`
`because Autumn is setting in here and colder nights.
`
`So RHR definitely affects the result. and | average 8 hrs sleep under the new sleep system..

`@NellyGJoin the genetic clan. My mother the same... She seemed to go all day, walking to the shopping
`
`Marathon Racer
`
`@ 9704 ¥ 845
`
`1@ 5469
`
`centres when | was 5 yrs old.. No car in those days. That was my legacy because my doctors, including my
`
`heart specialists over the years kepttelling me to blame my parents. The shopping centres weretypically
`
`4km (2.5 miles) 8km (5 miles) total there and back. And mum was pushing a pram with my younger sister.
`
`| can see mylittle legs going like mad..
`
`That legacy today is that | can walk at exercise speed, never get breathless and still talk if needed. On a
`
`30 minutes walk last night | accumulated 30 minutes of Very Active Minutes, 10 METS/minute on both my
`
`Surge and Blaze. HR was in the cardio zone and no erratic graphs. It surprised me, but | was walking at
`
`HiiT method using treking poles with rubber feet on pavementat 45 fast steps followed by 15 steps
`relaxed/slow.
`
`But like all of this, we should be cleared by our GP's and fortunately | had my heart assessed at my last
`
`annual check-up because my doctor has always been concerned about my low HR. Last night most of my
`
`sleep was 46-49bpm. It's 51 at 10pm while I'm typing this post. My RHR has come back to 51 over the last
`
`few days.
`
`Thanksforall of the enthusiastic forum posters who keep an eye on us....and Fitbit for helping and giving
`
`us the choice of tools to help us continue our quality oflife.

`
`@sfurry: did you also record your 12-minute Cooper's run on your Fitbit? If so, did it change your cardio
`fitness score? Of course, the problem with running on a track (loop)is thatit’s not optimal for getting the
`
`distance with GPS(especially with a phone’s GPS). Straight line would be better. Congrats in any case for
`
`getting 2450 meters, it’s very good for an "older" guy! In fact, most 20-somethings wouldn’t get that far.
