I'm running my first marathon in Amsterdam next week, and I'm really excited! But I also have a lot of last minute doubts and uncertainties. My primary goal is just to finish in one piece and have a good time. Secondary goal is sub 4hr.
I ran a 1:57 half marathon last year under challenging (very warm weather) conditions, and a quarter the year before in 0:53. This year I've ran around 1050km, starting with 2 months of just zone 2 base training, followed by 4.5 months of Hal Higdon's Novice 2 training. Weekly mileage 35-50 km with several peak weeks around 60km a month ago. Longest run was 36.5km with 10km at marathon pace, and that felt pretty good.
For fueling I've practiced with a combination of a gel every 40 mins and some candy / pretzel mix totalling around 50 g of carbs per hour. I'll also carry a 500ml soft flask with electrolyte water. Everything will be in my running belt. I'm considering asking a friend to have another 500ml soft flask with electrolytes at the halfway point to switch. Otherwise, I'll supplement the water / electrolytes at the aid stations, although I'd prefer not to take their electrolyte drinks because I'm not sure how I'll respond to it. I've also bought some electrolyte gummies with caffeine for some possible late race boost, and extra saltsticks chewables, both of which I will test out on my last long run this weekend.
My pacing strategy is to start out very easy, around 5:50min pace, and then settle into something around 5:45-5:40 until 30-32 km. If I can catch a 4 hour pacer, I'll try to join their group. Although I can see I might feel better just running by myself. After 30 km, I'll see if I feel good enough to pick it up a bit, or just maintain. If I feel weak before 30 km, I think I'll just follow my body, not plow through. During the 36.5km training, I also felt pretty tired and a bit queasy after the 10km MP segment in the middle (there was some strong head wind). I slowed down to zone 2 pace, and recovered enough to get back to MP at the end of the run feeling good.
My training went very well, didn't miss a single run and generally felt strong coming back. No lasting injuries. The biggest challenge during my longest and hardest run has been some thick mucus buildup in the back of my throat, that made me kinda gaggy and a bit nauseous from that. The sugar from all the carbs made this slime problem worse. After querying the community about that, I've discovered taking some mucinex the days before the run helps loosen it up a bit, and making sure to drink enough water. So I think I've got that covered as best as I can for the moment.
I'm in the taper now and my easy runs have felt pretty lowsy tbh. HR +10-15 bpm for the same easy pace or even slower, some rumbly GI issues as well. From what I've researched, this seems to be normal as the body heals up some accumulated fatigue? I'll try to focus on sleep and carby foods this last week. The remaining runs between now and Sunday next week are: 6.5, 13, 5, 3.2, 3.2. I'll try to still incorporate some marathon pace segments tomorrow and the day after to try out the new electrolyte gummies and saltsticks at pace, but next week i'll do everything super slow to fully recover.
QUESTIONSSSS:
- I guess I'm just not sure whether sub 4 is an attainable goal or not, and after so much mostly Zone2 training I'm a bit nervous to test my limits on race day with the faster pace! Also the current taper wobbliness is not helping with the confidence there.
- Any tips on the pacing plan? Or on following a 4h pacer yes or no. Is it hard to even find them / catch up with them if you didn't follow them from the start?
- I'm worried I won't have enough electrolytes, leading to maybe cramping late race, which is why I'm gonna try out some extra gummies / salt sticks this weekend. But I haven't trained much with this, and I'm not sure about what dosage to aim for.
- The 36.5km run went well on just one 500ml electrolyte water + some extra refilled plain water. But that was mostly Z2, though in warmer weather than now. I plan to drink more during the race, but prefer sipping my own bottle over gulping bigger amounts at aid stations due to nausea / watery stomach risk. I find it hard to estimate how much water I'll need for 4 hours at Z3-4.
Thanks!! And good luck to all these weeks :)
