Hi,
I am Garmin user for several years now. I am really disappointed with the fact that there was never a Marathon Training Plan update. We have the same plans for years without any kind of update. Repeating the same plan every year is quite boring. Also Garmin released a new running foot pod Powermeter, but no training plan specific for it.
To be honest I expect much more dynamic on that content. Garmin is releasing great new products, but somehow forgetting the platform behind.
Thanks,
Gustavo
