In reply to RockAngel:
Seems more than doable. Also, you do not need much gear for it (no sleeping equipment, no spare clothing or loads of food). I would be worried more about the ascent rather than the distance - keep going is not as difficult as ascending/descending.
You can also investigate on Naismith's rule, which can by adjusted by Tranter's correction. It has little to do with the real time (if you are not marathon runner, the time will vary* - more about it in the end), but it is quite accurate estimate.
I have done 7 Munros a day (West Cairngorms) with 3192m ascent (followed by 3217m descent) and 42km (26 miles). The ascent is as twice as much as in Yorkshire 3. Oh, and it was 8th day of trekking, with full 40l bag with a tiny tent, sleeping bag, over 2 kilos of food and a little bit of extra stuff. I did not run, enjoyed greeting some people and reindeer (

* Why Tranter's correction or Naismith's rule do not work? I think there are too many factors, including weather, terrain, mood, food, etc. I have logged two days (one easy day between them) with similar numbers:
5 Munros: +1780m, -2030m, 25.28km, Naismith's: 8h1m (West to Glenshee Ski Centre)
10 Munros: +1833m, -2115m, 40.8km, Naismith's: 11h13m (East to Glenshee Ski Centre)
However, both times it took 12h40m to finish. All differences I can remember are:
- The former day included more steep sections.
- The latter day I did not sleep well (if I feel sleepy, I do things faster).
- At the latter day I met few groups of soldiers (they had a challenge), so at few sections I kept a pace together with them.
- I was enthusiastic to do 10 Munros a day and get to Loch Callater bothy before dark. It was my first bothy ever.
- At latter day I ran out of water at noon and had to hurry a little bit. I did not alter the planned route.
