I'm relatively new to mountain marathons and haven't done an ultra yet. I've done endurance events in the last few years (such as an Ironman in 2016), Ring of Steall Race and Dark Mountain Marathon in 2017, with half marathon trail races a few times a year - so i'm clear on the commitment to training, but i'm not sure how long it takes to recover from the big events.
I'm considering doing the Mont Blanc Marathon on the 27th June next year, followed by the Eiger Ultra Trail (51km) on the 18th July. Both have about 3,000m of ascent. I'm just trying to work out whether I will have sufficient rest between them to enable me to turn up to the Ultra in July without any fatigue in my legs etc. Has anyone done something similar or can offer advice please?
Thanks in advance.
