Note that the quote in previous post that
@Tony Crocker attributes to me was from post by Rod2301. I edited my post and
put what I quoted in italics and tried to match the color of the link to make that clearer.
Sorry for getting so off-topic, but I will eventually mention Spain.
As I approach 70, I have not slowed down much but need to learn to avoid the one? hard crash each season that I've suffered in most recent years. When I hiked Highlands Peak in March this year, I took breaks when I saw heart rate on Garmin watch my son gave me for Christmas was getting over 130. (Note that American Heart Assoc. says Maximum Heart Rate is 220 minus your age.
AHA also says recommended training heart rate zone is 50-85% of max - for 60 years old is 80-136, for 65 is 78-132 and for 70 is 75-128.)
My wife and I have taken advantage of mild weather during most of the 2nd half of July in our usually very warm part of the SF Bay Area. My phone says I increased my miles walking from 3.6 per day in previous 17 days to 5.8 miles in the last 11 days. We want to work up to at least two consecutive days of 10 miles as in less than two months we will be doing 75+ miles in 6 days on a supported luxury Camino de Santiago tour from Baiona, Spain to Santiago de Compostela, where our last and longest day will be 16 miles.
Last Thursday, we parked inside the gate to my family's ranch and walked 5.25 miles with two 400' climbs. I carried a pruning saw as there was a tree down on edge of road requiring vehicles to go a little off road to get around it. 3-4 cuts of 2-3" diameter oak branches and it was gone.
Then about a half-mile down the road I found fallen branches totally blocking road.
In 20 minutes, I was able to clear enough that a vehicle could get through. I had to cut one limb that was 8-10" diameter and another that may have been 12" using pruning saw. When I took a break sawing and checked, I saw my heart rate was over 140. And even though temps were in the low-mid 70s, I jumped into water where we dam up creek every Spring not too far away to cool off.
