Which is more challenging?
36 years old
19:50 5k pr
133:58 half 'thon pr
Both set this year
40 miles per week
1 long, 1 speed, 1 tempo, 3 easy days
For my speed im doing time based: 3 minutes on,
3 minutes off x 6 sets.
Im hitting 5:40 -6:00 pace for the 3 minutes on.
Which if either of those goals can I expect to hit this year? Thanks (not trolling, just joking with the 'thon reference)
