1g per kg of bodyweight seems somewhat high (maybe it's more like 1g per kg of lbm?). I was under the impression that you could only process so many carbs per hour too, though I guess with gels and such they take a more direct route to your bloodstream.
That does sound high unless it's for climbing or something?
It might be worth a try, but the file on the Garmin is tiny, way smaller than the files for shorter rides. I guess I'll just have to go and climb that
awful hill again sometime!
Anyway. The Garmin worked for
this morning's short ride, so at least I know it's not busted.
You can repair garmin routes and adjust start/end points -
http://strava-tools.raceshape.com/snap/ (not one I've used, I used another but can't remember which before). It looks to work the same way - link your ride, 'fix it', export .gpx, upload to Strava.
Once I've recovered all the fitness I'm currently losing at least /brokenrecordwhining.
Chin up mate, I'm fairly sure you'll not be as bad as you fear! Aslong as you're not proper 'slobbing it' and eating chips for every tea you'll soon regain your fitness (if you lose much at all)
Took my new bike out on its first proper ride. 60 km and 750 m elev and got a fair few pbs. It doesn't make much difference up severe hills but you certainly notice the weight difference on slight rises especially when giving it the beans. Was a really smooth ride and just glides over the countless rough surfaces I encounter. Really pleased with it but a bit knackered now. My fitness feels as though its coming along though.
Nice and glad to hear it's riding well - I was similar with the switch to mine, from a cheap heavy alu to a light alu with carbon forks it felt sooo responsive and fast... Without making a huge difference to my riding and times I just found I wasn't as tired after every ride (finding it much easier to climb and do longer distances).
Good thinking on trying out the routes in advance. One of the Norwich clubs puts its routes up for the next few weeks and is clear on its expectations with regard to pace (15-16 avg in the steady group). I'll give some a try when I get my new bike and see how I get on.
Non-stop on my hybrid I can do 26 miles at a 15-16 mph average so I might be ok as their shortest route is 39 miles with a stop and a longer out and shorter return.
Lots of clubs will share their rides, 'stalking' some of the riders regularly spotted on Strava segments you ride can also be a good way to find some good routes. Would still be nice to have a feature within strava where you can put in distance/climbing/time and it looks through local rides for your criteria and matches routes for you... Then again we know how lax Strava are to add, change or even 'fix' things in their app! Slackers!

15 mph average seems a good starting point for most clubs beginner rides, I used to think that was hard but my riding has all been solo - riding as a group is easier so I imagine 15 mph average is easy enough.
After my 8 min FTP yesterday I was intending on going out for a ride today... I may still do so but 2 bottles of wine and a huge steak yesterday have made me feel very sluggish. Mrs' also slept on my arm overnight and now having problems straightening it! Drunken injuries without a drunken night out!

Also have a PC build to finish for a friend and all the usual weekend housework chores... Gah!
Edit:
Local sportive announced for 12th April, 56 miles. Bit too soon and too long a 'Full-Pint' distance for me (I think), no announcement of a 'Half-Pint' ride, but a free beer (allegedly) when you finish as it's sponsored by a popular local brewery! Maybe next year...
