My SO and I have run the welsh coast path and Offa's Dyke, all except for the bit between Port Talbot and Chepstow, which we are doing this July. I'll try and answer issues in the order you raise them.
- Distance. 120 miles if fine for 10 days. We are fairly leisurly and a 15-mile day could be over by early afternoon, even after a big breakfast in a B&B. I think you'd get comfortable with 20 to 30 km a day. This gives a lot more time for sightseeing than walkers get.
- Rest days: We used to have them but now to be honest we'd rather get on with it. Once you get used to it after 3 or 4 days then they're a bit pointless. If you want to plan them in for sightseeing that's another matter.
- Logistics. After carrying our own a bit we now use a baggage company that also books B&B and just carry a day sack.
- Training. If you're marathon-fit it won't be a problem, unless you never do any climbing. The answer depends on what sections you are doing. North Wales is mostly flat and a doddle. Pembs CP can be hilly and is better S to N for training purposes.
- Planning distance. If you look at some of the walker's schedules or guidebooks and choose the plan for an ambitious walker you will have a lot of time spare if you run a lot of it.
- Back-to-back is not a problem if you have restrained yourself. I tend to have a pulse monitor and mostly stay in as Easy zone in marathon terms.
- Peak days. After a few days you will be able to handle a peak day over 30 km but I wouldn't plan them in a row. From memory, the headland north of Fishguard is a long day with no break possibilities but by the time you get there S to N you'll manage it.
All the tracks are logged on Fetch, Starva and Garmin if you want pointers for any particular stretch. We did it in several 2 to 3 week chunks. Just ask if there's anything else we can tell you.
