I Ran Every Day for 69 Days: From Marcothon to the Winter Spine Challenge
At the end of November 2025, I had no intention of starting a running streak.
A few runs at the end of the month turned into a few more… and before I knew it, I rolled straight into Marcothon — the challenge to run every day in December.
After completing Marcothon for the 12th time, I could have quite happily stopped there.
Instead, I decided to keep going.
And that’s where things escalated slightly.
The Stats (At a Glance)
Here’s what the 69-day streak actually looked like:
- 28–30 Nov: 18.5 miles
- December (Marcothon): 203 miles
- January (Winter Spine Virtual): 269 miles
- 1–4 Feb: 29 miles
👉 Total: 519.5 miles in 69 consecutive days
Got to admit the film groundhog day really did spring to mind on many of the days….
From Marcothon to the Winter Spine Challenge
In January, I signed up for the Winter Spine Virtual Challenge.
This challenge is based on the brutal UK ultramarathon, the Spine Race, which follows the Pennine Way for 268 miles.
The virtual version keeps the same distance:
268 miles to be completed in January.
That meant one thing:
To complete it, I needed to average just over 8.5 miles every single day for the entire month.
And I decided to do it while continuing my daily running streak.
The Timeline
Here’s how it played out:
- 28 Nov – 30 Nov → 3 days running
- December → Marcothon (run every day)
- January → Winter Spine Virtual (268 miles)
- 1–4 February → streak continued
👉 Total: 69 consecutive days running
What the Winter Spine Challenge Actually Feels Like
The number sounds manageable on paper:
268 miles in 31 days
But the reality is different.
You’re not running fresh.
You’re carrying fatigue from December.
You’re running through:
- cold, dark winter days
- tired legs
- busy schedules
And you still need to find 8–10 miles every day.
Some runs are enjoyable.
Others are purely about getting the distance done.
The Physical Impact
After 40–50 days of running, things start to change.
Nothing dramatic — but noticeable:
- legs constantly feel “used”
- calves stay tight
- recovery becomes ongoing rather than complete
You’re no longer running fully fresh.
You’re running on top of fatigue.
The key becomes simple:
👉 Keep most runs easy
The Mental Side (This Is Where It Gets Interesting)
The biggest shift is mental.
Running stops being a decision.
It becomes automatic.
Even on days when:
- you don’t feel like it
- the weather is poor
- time is tight
…you still go.
By the time you reach 60+ days, you become oddly protective of the streak.
You don’t want to be the one who breaks it.
What You Learn Running Every Day
After 69 consecutive days, a few things become very clear:
Consistency beats everything
You don’t need perfect training.
You just need to keep showing up.
Easy running is the foundation
Most runs settle into a comfortable, sustainable effort.
This is where real endurance is built.
You become very aware of your body
You learn the difference between:
- fatigue
- tightness
- potential injury
Small wins matter
Some days the goal is simple:
👉 Get out. Run. Keep the streak alive.
Hydration for Winter Running (Especially for Heavy Sweaters)
One thing that stood out during the streak was how important hydration remained — even in winter.
Layering up can lead to significant sweat loss, even in cold conditions.
If you’re a heavy sweater, this becomes even more important over consecutive days.

The Reality of Finishing
By early February, I’d run for 69 consecutive days.
That included:
- Marcothon
- Winter Spine Virtual Challenge (268 miles)
And while there’s a sense of achievement…
There’s also a quiet appreciation for something simple:
👉 A rest day.
Would I Do It Again?
Probably.
Running streaks have a strange way of pulling you back in.
But they also remind you of something important:
👉 Rest is part of training too.
