I honestly didn't know how this would go as I haven't really done any speed work, but when the world gives you lemons, you make lemonade.
This out and back effort was pretty solid. A little mud on the first "flat" section before the big 2km climb. All good! I pushed forward and stayed strong climbing. A quick photo at the top before bombing (for me) back down.
20:48 to the rock at the top (turnaround spot)
17:23 back down to the blue t-blaze
38:11 total time.
The last 1km or so really hurt, and I tried to push as hard as I could. Just missed breaking the 38 min marker. All good! I'm happy with my effort.
