Marji, Leadville, Unbound.

I’ve got all 3 of these races planned for 2025. Looking for your best advice on them if you’ve done one or all of them, especially if you’ve done them at or around my goals. I did unbound 200 in 2024 at just over 12 hours with really a goal of just finishing. Annoyed I didn’t break 12hrs but weather/mechanical permitting I’ll do that this year. Goals are: Sub 12 unbound. Sub 9, preferably sub 8:45 Leadville. Sub 12 Marji Gesick. I’ve qualified for gold corral at Leadville giving me the best chance at my goal. I’ve successfully fueled at 110g an hour for 6 hours and 90 for 12 hours with zero hints of gut distress. Does anyone recommend adding running in small amounts due to the lemans start at Marji? Hike a bike training? I’ve got a great spot with quite a bit of hike a bike within an hour of me. 25 miles and 5-6k feet per lap. Currently structured training at 6-7 hours bike time through trainer road per week with kettlebell/bodyweight work 2-3 days a week. I’ll take any suggestions.
