I think aging may have something to do with it. ya think??
The comments on this board are RIDICULOUS to think that some doctor is going to know why a 67 yr cycler "needs a nap" after riding 30+ miles. This is something "only a doctor" would know!?? And apparently the OP is a doctor.
I'm only 61 and I am laying here totally trashed after 37 miles yesterday and 30 today. I can't move from the couch and I'm TOO TIRED to properly nap.
As these years go by we may have to slow down a bit. It gets tougher that's why in races or group rides the +60 crowd is pretty thin. We get weeded out over the years, illness or just plain tired. It gets harder and it's harder to keep it going.
I'm going to keep going as long as I can, but I can feel it. I was hoping to do 55mi today but i woke up trashed and I made the right decision to cut it down to 30.
