I'm 67 and have been inactive for many years and definitely out of shape due to surgeries (shoulder impingement last year and knee replacement 2 years ago). I recently decided to get in shape to complete one item on my bucket list before I'm 70. To hike to the top of California's Yosemite Half Dome mountain. It's a 17 mile (27k) hike with an elevation rise of 4800ft. (1460m). I figured one good way to get in shape is to do some long distance walking. I plan to enter some 10ks and I would also love to complete a half-marathon under the time limit.
I'd love to hear what some of you think about how realistic it is for me to enter and complete the Berlin Half-Marathon (I live in Berlin) on Aug. 22nd. The cut off time is 3 hours 15 minutes. My only goal is to finish under 3 hours 15 minutes.
Here is what I have been doing the last 2 1/2 weeks: Regular 4 mile (6.43km) walks 3 times a week. Week 1 I did a 7 mile (11.26km) walk. Week 2 I did a 8 mile (12.87km) walk. My fastest 4 mile pace is
