A little check up on Alula design, made me think small adjustements can be made especially regarding the last km incline which can have big impact for sprints (see yesterday -2% in TDU when it was probably not a real -2 there irl).
stage 1 : should be around 143kms and last km a 0%.
stage 2 : the finish line seems to be at the top of the climb, not mid climb. maybe add the last km ? I found info saying it's 1.6kms >12%; with a steeper part; but the last 500m are less steep. 14/10 seems a bit too much there imo; but probably not a big deal. I'd be keen to keep 2 steep kms ofc (13/9 or 9/13 f.e) but it would mean to adapt the whole circuit.
stage 3 : should be around 180kms, last km a 0%.
stage 4 : last km as a -1% is ok, -2% is a little more accurate, but no big deal. main question is 8 or 9km after the top of the climb ? you went for 8, that's ok. 9 would have been ok too. about the steep climb itself, I think there should be 3 sieb kms there, something like : 9-16-9 (or even 17% for the km in the middle), source I found :

stage 5 : stage should be a little longer and final circuit changed. last km is a -1% (or a -2% max) not a -3%. actually how I see the final kms (and part of the circuit) Something like : 2/4/-1/-2/-1 climb could also be seen at 1/5 as there is a steeper part, but it's super short, so 4% looks better there imo.
Another question is about the categorisation of the stages. Official website says flat for 5 stages, which is not a great idea imo. You decided to go for medium for stage2 and mountain stage4; could possible be the opposite. or both be mountain stages.
I hope this feedback can help you improving your designing techniques ECS in the future. and I hope this can help to adapt Alula ! All I said is ofc not pure truth as designing means to adapt and make choices sometimes.
